DETROIT (WWJ) – A Flint-area woman is facing charges after Secret Service agents caught her outside the White House with a gun.

April Lenhart, of Mount Morris, was taking part in a demonstration Thursday night as President Barack Obama addressed the nation on immigration, announcing plans to shield as many as 5 million immigrants from deportation.

The 23-year-old woman was part of a group protesting along the north fence line of the White House complex when she was spotted by plainclothes agents.

“Secret Service noticed she had a gun in a holster attached to her hip,” said WWJ Legal Analyst Charlie Langton. “She was taken in for questioning and arrested when it was found out that she did not have a license to carry that firearm.”

Authorities have not yet discovered a possible motive for Lenhart to have the gun because she is reportedly not cooperating with investigators.

Officials say the President was inside the White House at the time of the incident, although they do not believe he was in danger.
