Donald Trump was loudly booed by the crowd at Nationals Park in Washington, DC, Sunday during his first appearance as president at a Major League Baseball game.
The crowd also chanted "Lock him up!"
Trump, along with first lady Melania Trump and some GOP lawmakers, attended Game 5 of the World Series hours after he announced the death of ISIS leader Abu Bakr al-Baghdadi during a US raid in Syria.
At the end of the third inning of the Washington Nationals home game against the Houston Astros, the crowd cheered as the Jumbotron paid tribute to US service members.
The crowd's cheers immediately turned to resounding boos heard all around the ballpark when the announcer introduced Trump and the Jumbotron showed the president standing and clapping.
Trump continued to smile and clap.
Some sections of the crowd then began chanting "Lock him up!"
A few "Impeach Trump" banners were displayed across the upper decks.
Fans behind home plate brandished a sign reading "Veterans for Impeachment."
A White House spokesperson did not immediately return a request for comment. As of Monday morning, Trump had not tweeted about the game.
The Nationals lost the game 7–1.
