A woman with a gun was arrested outside the White House Wednesday night.
Secret Service officers saw April Lenhart, 23, with a 9 mm handgun and arrested her for having an unregistered firearm, the Washington Post reported.
CBS reported that Lenhart is from Michigan and was being "uncooperative." The Post added that Lenhart's motives were unknown Thursday night.
The arrest came just minutes after President Obama delivered a speech on immigration from the White House. According to CBS, Obama was still inside when the woman was taken into custody. The incident also happened as immigration reform advocates gathered outside the White House, though it was unclear if the woman's arrest was connected to gathering.
The arrest comes on the heels of a series of potential and actual White House security breaches, including the arrest of an Iowa man Wednesday.
The man, 41-year-old R.J. Kapheim, was arrested a block from the White House, ABC News reported. The man had been behaving suspiciously and a search of his car produced a rifle and ammunition.
On Sept. 19, Omar Gonzalez scaled the White House fence and made it inside the residence before Secret Service agents finally tackled him. Documents released earlier this month showed Gonzalez penetrated security by jumping into bushes, and because a Secret Service agent was talking on his cellphone at the time, among other things.
Gonzalez was armed with a knife, and investigators later found ammunition in his car.
