Former Title: Secretary of Homeland Security
Kirstjen Nielsen, the secretary of Homeland Security who played a major role in implementing the Trump administration’s key policy priority, immigration enforcement, resigned April 7.
In a letter to President Trump, Nielsen said that her resignation was effective immediately.
“It has been my great honor to lead the men and women of the Department as its sixth secretary. I could not be prouder of and more humbled by their service, dedication, and commitment to keep our country safe from all threats and hazards," she wrote.
Former title: Small Business Administrator
Linda McMahon resigned as Small Business Administrator in order to lead fundraising efforts for President Trump’s re-election at America First Action PAC.
Trump announced McMahon’s departure during a press conference at Mar-A-Lago on March 29, saying “She’s going to go and help us with a very, very important year and a half that we have coming up. The re-election, as they call it.”
McMahon, the former CEO of World Wrestling Entertainment who ran two failed bids for the Senate in Connecticut, was a prominent donor to Trump’s election efforts in 2016.
She was one of five women in Trump’s cabinet, and has served since the beginning of the Trump administration. She has maintained a relatively low profile during her tenure. Trump thanked her saying, “It was just so smooth.”
Trump said that McMahon’s replacement would be announced shortly. McMahon wrote in a separate statement that her last day would be April 12.
Former title: Assistant to the President and Communications Director
Bill Shine, the controversial former Fox News executive, who was hired as Trump's top communications aide in July 2018, resigned his post on March 8.
Shine was ousted from Fox News following the network's mishandling of sexual harassment in May 2017.
"Serving President Trump and this country has been the most rewarding experience of my entire life," Shine said in a statement. "To be a small part of all this President has done for the American people has truly been an honor. I’m looking forward to working on President Trump’s reelection campaign and spending more time with my family."
Former title: Food and Drug Administration Commissioner
Food and Drug Administration Commissioner Scott Gottlieb resigned on March 5, 2019 in a surprising departure from the Trump Administration.
Gottlieb, 46, was sworn into leadership of the $5.1 billion agency in May 2017, and had generally been seen as a quiet and effective leader. He had previously served at FDA during the second Bush administration as a deputy commissioner, with a background as a physician and public health policy expert.
In a letter to the FDA staff that was also posted on Twitter, Gottlieb said that he wanted to spend more time with his family.
Former title: FEMA Administrator
FEMA Administrator Brock Long announced he is stepping down from his role after two years of leading the agency.
In a tweet posted Feb. 13, Longer wrote that it has been "a great honor to serve our country" as the FEMA administrator.
"While this has been the opportunity of a lifetime, it is time for me to go home to my family," he wrote.
Long has led the federal government's response to a number of natural disasters, including Hurricane Maria which devastated Puerto Rico in 2017. The hurricane left a large part of the island without electricity for several months and led to the death of nearly 3,000 people.
Democrats have pushed to investigate the government's response to Hurricane Maria. Senator Kirsten Gillibrand announced in January that she wants to introduce a bill that would have an independent commission "investigate exactly how and why the federal government abandoned its responsibilities and turned its back on Puerto Rico."
Former title: Secretary of Defense
Jim Mattis will resign from the Trump administration at the end of February, the president announced in a tweet.
"During Jim’s tenure, tremendous progress has been made, especially with respect to the purchase of new fighting equipment. General Mattis was a great help to me in getting allies and other countries to pay their share of military obligations. A new Secretary of Defense will be named shortly. I greatly thank Jim for his service!" Trump said.
The 67-year old former general, who led a Marine division to Baghdad during the 2003 invasion of Iraq, was until the final months considered a steady presence in Trump’s volatile cabinet.
But he and the president differed internally over several topics, most recently Trump's decision to remove troops from Syria.
In his resignation letter, Mattis said the US's strength is "linked to the strength of our unique and comprehensive system of alliances and partnerships" — many of which Trump has questioned or pulled out from.
"Because you have the right to have a Secretary of Defense whose views are better aligned with yours," Mattis wrote, "I believe it is right for me to step down from my position."
Former title: US Secretary of the Interior
Secretary Ryan Zinke is leaving the Interior Department at the end of 2018.
Zinke arrived his first day on a horse. He’s leaving with less flourish — under scrutiny for possible financial conflicts in a Montana land deal, his decisions to shrink certain national monuments, and more.
“Secretary of the Interior @RyanZinke will be leaving the Administration at the end of the year after having served for a period of almost two years,” the president tweeted on Saturday morning. “Ryan has accomplished much during his tenure and I want to thank him for his service to our Nation.”
Although Zinke took over the Interior in March 2017 after a relatively smooth confirmation process, his tenure at the agency that oversees public lands has been steeped in controversy — from the Montana kickbacks to reshuffling the agency’s climate scientists to plotting a massive agency restructuring.
"I love working for the President and am incredibly proud of all the good work we’ve accomplished together," Zinke tweeted on December 15. "However, after 30 years of public service, I cannot justify spending thousands of dollars defending myself and my family against false allegations."
Former title: White House chief of staff
John Kelly, who has been President Donald Trump’s chief of staff since last July, will be leaving the White House by the end of the year, the president announced on December 8.
“John Kelly will be leaving toward the end of the year,” Trump told reporters as he left for the 119th Army–Navy football game in Philadelphia, describing him as "a great guy."
The abrupt announcement of Kelly's departure came a day after widespread reports that the chief of staff was on his way out amid a frosty relationship with the president.
There had been semiregular panics about Kelly’s coming divorce with Trump basically since the moment he took the job. At the end of July, Kelly told White House staff that he planned to stay in his role until the end of the 2020 presidential election and that Trump wanted him to stay on even longer. But that agreement was never taken seriously inside and outside the White House and became even more precarious after the midterm elections.
Former title: Attorney General
Attorney General Jeff Sessions submitted his resignation to President Donald Trump on November 7, via a letter hand-delivered to Chief of Staff John Kelly. Sessions wrote that he was submitting his resignation at the president's request.
Sessions was the first sitting US senator to endorse Trump during the campaign, but over the past year he became an object of the president's ire for his decision to recuse from the US Department of Justice’s investigation into Russian influence in the 2016 election. Trump reportedly expressed his dismay in private at first, but his frustration spilled into the public sphere, with Trump openly, and repeatedly, criticizing Sessions to reporters and on Twitter.
Former title: US Ambassador to the UN
President Donald Trump said Nikki Haley, US Ambassador to the UN, would leave her role by the end of the year to "take a little time off."
"She's done a fantastic job, and we've done a fantastic job together," Trump said. He added that she "has been very special to me," that she would be welcome back into his administration, and that they would keep in "constant touch."
Haley has been one of the Trump administration's leading foreign policy voices, but her more hawkish views have at times clashed with the president’s vision.
Haley said the job has been "an honor of a lifetime" and praised the president and his family, specifically calling out Jared Kushner as a "hidden genius" and Ivanka Trump as a "great friend."
Haley said she does not plan to run in the 2020 election, adding that she will campaign for Trump's reelection.
Former title: Speechwriter and policy development aide
Darren Beattie, a policy aide and speechwriter to President Donald Trump, left the White House in August 2018 after CNN reported that Beattie had spoken alongside several prominent white nationalists at a 2016 conference. The Washington Post reported that Beattie refused to resign and was subsequently fired.
In a statement to BuzzFeed News on August 19, White House spokesperson Hogan Gidley confirmed that "Mr. Beattie no longer works at the White House."
Beattie had defended his appearance at the H.L. Mencken Club's conference to CNN, asserting that he said "nothing objectionable" and stood by his talk, titled "The Intelligentsia and the Right." He said that he continued to support Trump, whom he called "a fearless American hero." He previously worked as an lecturer at Duke University.
Former title: Director of the Office of Legislative Affairs
Marc Short, the White House's lead ambassador to Congress, is leaving the Trump administration in July.
“Marc was an integral part of the White House staff," White House chief of staff John Kelly said in a statement announcing his departure.
Short, who came to the administration after years of working for more establishment Republican figures, helped steer the 2017 tax law through Congress. He's also been a frequent face for the administration's legislative work on cable news. In the statement announcing his exit, he said he would be "forever indebted" to Trump and Vice President Mike Pence after working on the 2016 campaign and being part of the administration's first year in office.
Short is joining the University of Virginia's Miller Center for Public Affairs as a senior fellow, beginning in August.
Former title: Environmental Protection Agency Administrator
Scott Pruitt, one of President Donald Trump’s most controversial and effective cabinet secretaries, resigned from the Environmental Protection Agency after months of unending ethical scandals.
Pruitt has faced heavy scrutiny for potential ethical lapses tied to his spending, housing, treatment of staff, relationships with energy leaders, and travel on the job. A federal watchdog in April found the EPA violated two laws when it spent $43,000 on a secure phone booth for Pruitt without first seeking permission from Congress. The White House’s Office of Management and Budget has also announced an investigation into the purchase.
Pruitt has drawn scrutiny for asking aides to assist with his wife’s job search, including approaching Chick-fil-A; using his staff to run errands for him, like getting fancy lotion sold at Ritz-Carlton hotels and looking into getting a used mattress from the Trump International Hotel for Pruitt’s own use; and for the EPA reportedly “scrubbing” his public calendar of certain meetings.
The president announced Pruitt's resignation in a tweet June 5.
Former title: Deputy Director of the National Economic Council and Deputy Assistant to the President for International Economic Affairs
Everett Eissenstat, a top trade adviser to the Trump administration, is leaving the White House in July.
"Everett was a consummate professional and a valued member of the White House staff," chief of staff John Kelly said in a statement. “We will miss his deep expertise, commitment to duty, and skillful management of the National Economic and National Security Council’s international team."
Former title: Deputy Chief of Staff for Operations
Joe Hagin, a top aide to President Donald Trump, will be leaving the White House in July, an announcement that comes a day after BuzzFeed News reported he had previously worked with key backers of an alleged "sex cult."
Hagin, the deputy chief of staff for operations, played a key role in organizing the president's summit with North Korean leader Kim Jong Un in Singapore.
"Joe Hagin has been a huge asset to my administration," Trump said in a statement. He added, "We will miss him in the office and even more on the road."
Former title: White House aide
Kelly Sadler, the White House aide who joked that Sen. John McCain's opposition to President Trump's nominee for CIA director didn't matter because "he's dying anyway," no longer works in the administration, the White House confirmed.
The circumstances, or reasons, surrounding Sadler's departure were not immediately clear. The New York Times reported that it came after an ongoing feud with another staffer, and not because of Sadler's comment about the Arizona senator.
“Kelly Sadler is no longer employed within the Executive Office of the President," Raj Shah, a White House deputy press secretary, said in a statement.
In May, Sadler joked during a closed-door meeting with about two dozen staffers about McCain's brain cancer.
"It doesn't matter," Sadler reportedly said, referring to McCain's opposition to Gina Haspel, who had been nominated to head the CIA. "He's dying anyway."
Former title: White House lawyer
Ty Cobb, the White House lawyer who has overseen legal issues related to the investigation into Russian interference in 2016's presidential election, is leaving the White House at the end of May.
"For several weeks Ty Cobb has been discussing his retirement, and last week he let Chief of Staff [John] Kelly know he would retire at the end of this month," the White House said in a statement on May 2.
Emmet Flood, a veteran white-collar defense lawyer who represented president Bill Clinton in his impeachment proceedings, will be taking Cobb's place.
Former title: Deputy National Security Adviser
Deputy National Security Adviser Rick Waddell plans to step down from his position in the White House.
"He will stay on board for the immediate future to help ensure a smooth and orderly transition," White House spokesperson Lindsay Walters said in a statement. "Dr. Waddell is highly respected and very well liked within the White House and the United States Army. We thank him for his continued service."
Waddell is the fourth national security official to leave since John Bolton became national security adviser earlier this week.
Former title: Deputy National Security Adviser for Strategy
Nadia Schadlow, the US deputy national security adviser for strategy, resigned April 11 and will leave the White House at the end of the month, CNN reported.
Schadlow is the third national security official to exit the White House after John Bolton was named national security adviser.
“The administration thanks Dr. Schadlow for her service and leadership in crafting the President’s 'America First' National Security Strategy,” White House spokesman Raj Shah said in a statement. "The strategy has set a strong foundation going forward for protecting the homeland, promoting American prosperity, preserving peace through strength, and advancing American influence. We wish Nadia and her family the best."
Former title: Assistant to the President for Homeland Security and Counterterrorism
The White House announced on April 10 that Tom Bossert is leaving his post as homeland security adviser to the president.
The announcement came just a day after John Bolton officially joined the White House as the president's third national security adviser. Bolton is reportedly looking to create his own security team. Bossert, who has been one of Trump's most prominent security advisers since the start of his administration, served as deputy homeland security adviser under President George W. Bush.
Bossert has frequently gone on TV as a face of the administration and appeared on ABC News just days before his announced exit, saying he was highly involved with the White House's response to a new apparent chemical weapons attack in Syria.
Sarah Huckabee Sanders, the White House press secretary, confirmed Bossert's departure.
“The president is grateful for Tom’s commitment to the safety and security of our great country. Tom led the White House’s efforts to protect the homeland from terrorist threats, strengthen our cyber defenses, and respond to an unprecedented series of natural disasters. President Trump thanks him for his patriotic service and wishes him well,” she said.
Last August, Bossert was tricked by an email prankster who made him believe he was emailing Jared Kushner.
Former title: Secretary of Veterans Affairs
President Trump's secretary of Veterans Affairs, David Shulkin, was pushed out of his position on March 28.
Trump plans to nominate White House physician Ronny Jackson to replace Shulkin, a holdover from the Obama administration. The post needs Senate confirmation, however, and will be temporarily held by Under Secretary of Defense for Personnel and Readiness Robert Wilkie.
In a New York Times op-ed, Shulkin blamed his exit on people inside the department who advocate privatizing the VA. "I believe differences in philosophy deserve robust debate, and solutions should be determined based on the merits of the arguments," he wrote. "The advocates within the administration for privatizing VA health services, however, reject this approach. They saw me as an obstacle to privatization who had to be removed. That is because I am convinced that privatization is a political issue aimed at rewarding select people and companies with profits, even if it undermines care for veterans."
Former title: National Security Adviser
National Security Adviser Gen. H.R. McMaster was replaced by former President George W. Bush's United Nations ambassador, John Bolton, in March.
“After thirty-four years of service to our nation, I am requesting retirement from the U.S. Army effective this summer, after which I will leave public service," McMaster said in a statement sent out by the White House. "Throughout my career it has been my greatest privilege to serve alongside extraordinary servicemembers and dedicated civilians." He thanked Trump for "the opportunity to serve him and our nation."
Trump named McMaster, a three-star general and a veteran of both Iraq wars, as his national security adviser in February 2017, a week after firing McMaster's predecessor, Michael Flynn, following reports that he had misled Vice President Mike Pence about conversations Flynn had had with the Russian ambassador about sanctions.
Trump has asked McMaster to stay on until mid-April, when Bolton takes the position.
Former title: Deputy Director of the FBI
Attorney General Jeff Sessions fired Andrew McCabe, the former deputy director of the FBI, in March, two days before his scheduled retirement.
McCabe, a career agent who briefly served as acting director of the FBI after President Trump fired James Comey from the job last year, was scheduled to retire after 21 years of working at the agency.
"I am being singled out and treated this way because of the role I played, the actions I took, and the events I witnessed in the aftermath of the firing of James Comey," McCabe said in a statement. "This attack on my credibility is one part of a larger effort not just to slander me personally, but to taint the FBI, law enforcement, and intelligence professionals more generally. It is part of this administration’s ongoing war on the FBI and the efforts of the Special Counsel investigation, which continue to this day. Their persistence in this campaign only highlights the importance of the Special Counsel’s work."
A little more than two hours after the news broke, Trump himself weighed in in a late-night tweet, calling the firing "[a] great day for Democracy."
Former title: Secretary of State
President Trump announced via Twitter he had fired Secretary of State Rex Tillerson in March, ending one of the shortest and most tumultuous tenures of a secretary of state in recent history.
"Thank you to Rex Tillerson for his service!" Trump said in a tweet.
That tweet was reportedly news to Tillerson. White House chief of staff John Kelly called Tillerson just days before, the Associated Press reported, and told him to expect a presidential tweet about him. But Kelly did not explicitly say the tweet would announce he was out of a job. Under Secretary of State Steve Goldstein told CNN that Tillerson learned he was officially fired from the president's morning tweet.
"All of us, we know, want to leave this place as a better place for the next generation. I'll now return to private life as a private citizen, as a private American, proud of the opportunity I've had to serve my country," Tillerson said.
Former title: Chief economic adviser
Gary Cohn — the president's chief economic adviser and one of the few administration officials directly involved with negotiating the biggest legislative success to date of of Trump's presidency, the tax cuts — left the White House in March.
“Gary has been my chief economic adviser and did a superb job in driving our agenda, helping to deliver historic tax cuts and reforms and unleashing the American economy once again,” Trump said in a statement. “He is a rare talent, and I thank him for his dedicated service to the American people.”
Cohn, a former Goldman Sachs president, was the subject of job speculation for months. There were reports dating back to last summer that his time in the White House would soon run out. Cohn was rumored as a likely candidate to replace Janet Yellen as chair of the Federal Reserve. That honor ultimately went to Jerome Powell. Most recently, there were reports that Cohn was one of the contenders in line to replace White House chief of staff John Kelly, whom Trump has soured on.
Trump named Larry Kudlow, a conservative commentator on cable news, to replace Cohn.
Former title: Personal aide to the president
John McEntee was escorted off White House grounds in March. According to the Wall Street Journal, he was under investigation for financial problems related to online gambling and mishandling of his taxes.
McEntee went to work for Trump's reelection campaign. According to a campaign press release, which praised him as "outstanding" and a "proven leader," McEntee will be serving as senior adviser for campaign operations.
Former title: Communications director
White House communications director Hope Hicks — one of the few longtime aides to President Donald Trump to make it to his second year in office — resigned in February. Her last official day at the White House was March 29.
"There are no words to adequately express my gratitude to President Trump," Hicks said in a statement sent by the White House. "I wish the president and his administration the very best as he continues to lead our country."
Her departure came days after she met with the House Intelligence Committee, which is investigating Russia's interference in the election, where she reportedly did not answer some of the committee's questions about her work in the White House or during the presidential transition. According to the New York Times, she said she has occasionally told "white lies" on behalf of the president, though she said that did not extend to anything concerning the Russia investigation.
Former title: Speechwriter
David Sorensen resigned from his position as a White House speechwriter in February after he was confronted about allegations he was abusive to his ex-wife during their marriage.
"Before we were contacted by the media, we learned last night that there were allegations," said deputy press secretary Raj Shah in a statement to BuzzFeed News. "We immediately confronted the staffer, he denied the allegations, and he resigned today."
Sorensen's former wife, Jessica Corbett, told the Washington Post that during their marriage Sorensen ran over her foot with a car, put out a cigarette on her hand, threw her into a wall, and grabbed her by the hair while they were out at sea on a boat.
Sorensen, in a statement to the Post, denied the allegations.
"In fact, I was the victim of repeated physical violence during our marriage, not her," he told the Post, adding that he was "considering legal options to address her defamation."
Former title: White House staff secretary
White House staff secretary Rob Porter resigned in February after his two ex-wives told the Daily Mail he had abused them.
Porter's ex-wives claim he was physically and emotionally abusive. His first wife, Colbie Holderness, alleged to the Daily Mail that he had punched her during a trip to Florence in the early 2000s. The Daily Mail posted pictures of Holderness with a bruised face.
Porter denied the allegations in a statement, calling them "simply false."
The Trump administration struggled to provide clear answers on who knew what and when regarding the allegation. White House officials offered contradictory information, leading to a confusing narrative and dribs and drabs of information from the news media. Read a timeline of the scandal.
George David Banks
Former title: Senior official on the National Economic Council
George David Banks, who served as special assistant to the president for international energy and environmental policy, resigned in February after he was told he would not receive permanent security clearance due to his past marijuana use, according to Politico.
Former title: Director of Centers for Disease Control and Prevention
Brenda Fitzgerald, the director of Centers for Disease Control and Prevention, resigned from her role at the agency in January after reports that she bought and sold tobacco stock on the job.
Politico reported that Fitzgerald had traded tobacco stock, including shares in an international tobacco giant, Japan Tobacco, after assuming the lead role at the public health agency in July. The US Department of Health & Human Services told Politico that the investments were made by a financial manager.
Fitzgerald's departure was announced by HHS in a statement, citing financial conflicts of interest.
"Dr. Fitzgerald owns certain complex financial interests that have imposed a broad recusal limiting her ability to complete all of her duties as the CDC director. Due to the nature of these financial interests, Dr. Fitzgerald could not divest from them in a definitive time period," HHS spokesperson Matt Lloyd wrote in the statement.
Omarosa Manigault Newman
Former title: Assistant to the president and director of communications for the White House Office of Public Liaison
It was announced that Omarosa Manigault Newman was leaving the White House in December 2017. Her departure formally went into effect Jan. 20, 2018.
Manigault Newman left her position under dramatic circumstances, with several outlets reporting that she was fired and escorted out of the White House at night, although she later denied this version of events. Press secretary Sarah Huckabee Sanders said the aide left "to pursue other opportunities."
Following her departure, Manigault Newman went on to appear on the first celebrity version of the US reality television series Big Brother.
Former title: Secretary of Health and Human Services
Tom Price resigned his cabinet post on Sept. 29 amid an expenses scandal surrounding his use of extravagant air travel.
"Secretary of Health and Human Services Thomas Price offered his resignation earlier today, and the president accepted," White House press secretary Sarah Huckabee Sanders said in a statement.
Price's resignation comes after President Trump had signaled his displeasure with his health secretary for days.
Price spent more than $400,000 in federal money for official trips on private jets 26 times since early May, Politico has reported. Two of those trips were to areas where he owns real estate, and to visit family members and longtime colleagues, the site also reported. Each private jet trip can cost taxpayers around $25,000.
Former title: Deputy assistant to the president
Sebastian Gorka, an adviser to President Trump, exited the White House on Aug. 25.
Gorka, a deputy assistant to the president, is known for his focus on Islamic terrorism and as a frequent presence on cable news. He previously worked as an international news editor at the right-wing outlet Breitbart, under the leadership of Steve Bannon — the onetime chief strategist to President Trump who has since returned to Breitbart.
A White House official suggested that Gorka had been pushed out. "Sebastian Gorka did not resign, but I can confirm he no longer works at the White House," the official said in a statement to reporters.
Former title: Chief strategist
Steve Bannon was out as President Trump's controversial chief strategist as of Aug. 18.
"White House Chief of Staff John Kelly and Steve Bannon have mutually agreed today would be Steve's last day. We are grateful for his service and wish him the best," said White House Press Secretary Sarah Huckabee Sanders.
The New York Times first reported that Trump had decided to remove Bannon but that he was still deciding how to do so. ABC News and NBC News later reported that Bannon was out, with ABC News saying he resigned two weeks ago. Bannon would not immediately confirm the reports to BuzzFeed News.
Bannon has functioned as a tie between the administration and the nationalist faction in Trump's base.
His fall comes after a tumultuous week at the White House, and for his place in it. Bannon was privately pleased with Trump's response to last weekend's white nationalist violence in Charlottesville, Virginia, which the president initially blamed on "many sides."
Bannon recently gave an explosive, on-the-record interview with the left-wing American Prospect, where he railed against White House adversaries and appeared to undercut the president's messaging on North Korea.
Former title: Communications director
Length of service: 10 days
Anthony Scaramucci was ousted on July 31, minutes after John Kelly took the oath of office as White House chief of staff.
Scaramucci repeatedly told reporters that he was willing to "fire everybody" in the White House communications office to stop leaks to the press from administration staffers.
During his short tenure, he also called New Yorker reporter Ryan Lizza and went on an expletive-laden rant about then chief of staff Reince Priebus and Trump adviser Steve Bannon.
Former title: Chief of staff
Length of service: 189 days
Reince Priebus was replaced as White House chief of staff by Homeland Security Secretary John Kelly, Trump announced in a Tweet on July 28.
"I am pleased to inform you that I have just named General/Secretary John F Kelly as White House Chief of Staff," Trump tweeted. "He is a Great American and a Great Leader. John has also done a spectacular job at Homeland Security. He has been a true star of my Administration."
Priebus told CNN that he offered Trump his resignation after he and the president talked about the administration's direction. White House press secretary Sarah Huckabee Sanders told reporters that the president and Priebus had been discussing the timing of his departure for about two weeks.
Former title: National Security Council adviser
Retired Col. Derek Harvey was removed as an adviser on the National Security Council on July 28.
Harvey was appointed by Michael Flynn and served as the council's senior director for the Middle East.
Former title: Press secretary
Length of service: 182 days
Sean Spicer resigned as White House press secretary on July 21, minutes after Trump hired Anthony Scaramucci to be the administration's new top communications official.
Spicer's tenure was marked by a rocky relationship with the media. He often made false statements during White House press briefings — something that was routinely parodied on Saturday Night Live.
His tenure was among the shortest ever for a press secretary.
"It's been an honor & a privilege to serve @POTUS @realDonaldTrump & this amazing country. I will continue my service through August," Spicer tweeted.
As of July 31, Spicer has still been at the White House.
Former title: Communications director
Length of service: 86 days
Mike Dubke resigned as White House communications director on May 30, citing "personal reasons."
“But it has been my great honor to serve President Trump and his admin," he wrote in his resignation letter. "It has also been my distinct pleasure to work side by side, day by day, with the staff of the communications and press depts. This White House is filled with some of the finest and hardest working men and women in the American government."
Former title: FBI Director
Length of service: 109 days
President Trump suddenly fired FBI Director James Comey on May 9 after a memo from top Justice Department officials argued the bureau had suffered "substantial damage" under Comey's tenure.
Trump later told NBC News' Lester Holt that he was thinking about the FBI's investigation into Russian interference in the US election when he decided to fire Comey.
Since then, Comey has testified before the Senate Intelligence Committee regarding his interactions with Trump. Read more about that here.
Former title: Deputy National Security Adviser

K.T. McFarland was asked to step down from her role as the White House's deputy national security adviser on April 9.
She has since been nominated to become the next US Ambassador to Singapore.
Former title: Deputy chief of staff
Katie Walsh — a longtime adviser to Reince Priebus — served as the deputy chief of staff until March 30.
She has since returned to a senior role within the Republican National Committee.
Former title: National Security Adviser
Length of service: 23 days
Michael Flynn resigned as the administration's national security adviser on February 13 after he misled Vice President Mike Pence about his conversations with the Russian ambassador Sergey Kislyak.
Flynn fielded accusations that he had discussed sanctions with Kislyak as a private citizen in December. Pence publicly defended the retired general, but reports said Flynn lied to the vice president about his conversations with the ambassador.
Sean Spicer said at the time that Trump asked for Flynn's resignation because trust between the two had "eroded."
Former title: Acting Attorney General
Length of service: 10 days
Trump fired Sally Yates 10 days after his inauguration after she ordered Justice Department lawyers not to defend the president's refugee and travel ban.
In a letter sent to department lawyers before she was fired, Yates wrote, "[F]or as long as I am the Acting Attorney General, the Department of Justice will not present arguments in defense of the Executive Order," adding that she was "not convinced" that defending the order squared with her responsibility as head of the Justice Department "to always seek justice and stand for what is right."
