WASHINGTON (AP) — A White House staffer is charged with firing the service weapon of an off-duty U.S. Capitol Police officer in what authorities described as a domestic incident. No one was hurt.

Prince George's County Police say officers were called to an Upper Marlboro, Maryland, home early Friday for a reported shooting.

Authorities say 37-year-old Barvetta Singletary had argued with the Capitol officer. Police say Singletary grabbed the officer's service weapon from a bag and fired one round, which hit the floor.

Singletary, a special assistant to the president and legislative liaison at the White House, is charged with assault and reckless endangerment.

A statement says Singletary was put on unpaid leave and her access to the White House has been revoked.
