A Washington, D.C., woman was arrested Friday while trying to bring a loaded handgun into the Cannon House Office Building as members were getting ready to leave for their August recess.

At 12:21 p.m., Capitol Police found the handgun at the bottom of a suitcase that was carried through security by Kimberly D. Barber, according to a Capitol Police weekly arrest summary released Wednesday.

The 34-year-old was charged with unlawful possession of a weapon, the report stated.

Barber made her first appearance in D.C. Superior Court on Wednesday, where she pleaded not guilty to the charge, according to court documents.

According to court documents, investigators said Barber told police: “I was advised by my boss Brossy, Jackson to bring two suitcases, one belonging to senior police officer Silversmith, Arnold of the Navajo Nation Police Department to the Cannon House Office Building located at 25 Independence Ave., SE. I went through security screening and a gun was found to be inside one of the suitcases. I was unaware that there was gun in the suitcase.”

Jackson Brossy is executive director of the Navajo Nation Washington Office. He could not immediately be reached for comment.

Further investigation determined that Silversmith had not informed Barber that there was a weapon in the suitcase, according to the court documents.

Barber’s next court appearance is scheduled for Sept. 11.

The incident occurred at the northeast door of the building. About an hour after the arrest, the House completed all legislative business for the week.

Capitol Police arrested a member of the Marine Corps congressional fellowship program in 2015 for having a loaded handgun. It was found in his vehicle during a routine vehicle inspection outside the Rayburn House Office Building.

The congressional fellow was charged with carrying a pistol without a license, and possession of unregistered ammunition and an unregistered firearm.

In 1999, former Donald Trump campaign manager Corey Lewandowski was charged with a misdemeanor when he tried to bring a handgun tucked into the bottom of a bag of laundry into the Longworth House Office Building. Lewandowski was working as deputy chief of staff to Ohio Republican Rep. Bob Ney at the time.
