A White House staffer threatened her boyfriend, a U.S. Capitol Police officer, with his own weapon during an argument, according to police.

According to charging documents, Barvetta Singletary sent her boyfriend a text on Friday, asking him to come to her Upper Marlboro home for sex. After they had sex, Singletary confronted her boyfriend about the other woman he was dating.

Investigators say Singletary asked her boyfriend to step outside, and they both went to his car. Once inside the car, Singletary asked to see her boyfriend's cellphones, police said. When he refused, Singletary reached into his bag and retrieved two cellphones and the victim's .40-caliber Glock 23 service weapon, charging documents state.

Singletary ran back into her home, and the victim followed, pleading with her to return his weapon.

Singletary demanded that the victim give her the passwords to the phones, but he refused, police said.

Singletary then pulled the gun out of its holster, pointed it at the victim and said, "You taught me how to use this. Don't think I won't use it," the arrest warrant said.

When the victim again refused to give her the passwords, Singletary said, "Your phone is more important than me holding the gun on you."

Singletary pointed the gun in the victim's direction and fired one round into the sofa where the victim was sitting, police said.

Fearing for his life, the victim ran away from the home. The victim told police he saw Singletary wipe the gun down with a towel. He then called 911.

Singletary was arrested at the scene without incident. She is charged with first and second degree assault and reckless endangerment..

Singletary is currently a Special Assistant to the President and House Legislative Affairs Liaison

A White House spokesperson said Singletary has been placed on unpaid leave, and her access to the White House complex has been revoked until they have more information.
