Police say a White House staffer fired a gun at her U.S. Capitol police officer boyfriend when he refused to let her see his phones.

Authorities say that Barvetta Singletary, a special assistant to President Barack Obama, demanded to see her boyfriend’s cellphones amid an argument about another woman that he was seeing. When he said no, she grabbed the phones – and his service weapon.

An arrest warrant alleges that Singletary told her boyfriend, “You taught me how to use this. Don't think I won't use it.”

Singletary then allegedly fired one round at the sofa that her boyfriend was sitting on. He fled and called 911.

The suspect, who made $126,000 last year as a White House staffer, has been placed on unpaid leave for the time being.

“We are aware of the matter and have temporarily placed the employee in question on unpaid leave and revoked her access to the complex until we have more information. We will take additional actions as needed,” the White House said in a statement.

Singletary faces a number of charges, including first- and second-degree assault and reckless endangerment.
