Reports of gunfire in Capitol Office building

US police sealed off the Capitol today after receiving reports of gunfire in a House office building across the street.

Capitol police are investigating “the sound of gunfire in the garage level of the Rayburn House Office Building,” said an announcement on the internal Capitol voice alarm system.

The Senate was in session at the time, but the House was not.

Representative Peter Hoekstra, conducting a House Intelligence Committee hearing, interrupted a witness to request those attending the meeting to remain in the room and said the doors must be closed.

“It’s a little unsettling to get a Blackberry message put in front of you that says there’s gunfire in the building,” he said.
