No one is allowed to enter or exit any of the buildings in the congressional complex. Anyone outside was advised to “seek cover immediately,” local media reported.
Shots were reportedly fired at the Capitol Visitor Center, an underground facility on the east side of the main building.
One police officer was shot, but “not seriously,” according to the Capitol’s Sergeant at Arms Frank Larkin. He said the shooter has been caught, but the shelter-in-place order remained in effect.
Subsequent reports said the officer was not shot, but maybe injured by debris, and had been treated at the scene. Reports of injured civilians have not been confirmed. The White House was placed on lockdown as well.
Shelter in place “remains in effect” while the Capitol Police investigate the incident, the Sergeant at Arms told Roll Call around 3:20 p.m. local time. The lockdown was officially lifted half an hour later.
According to NBC correspondent Pete Williams, the suspect entered the Capitol Visitors’ Center and pointed a gun at the police officer, who took him down with a single shot. The suspect has been taken to an area hospital.
Citing unnamed sources at the Capitol, NBC later reported that the suspect pulled out his weapon when it triggered the metal detector inside the visitor center.
Initial reports of a shooter caused some confusion because the Capitol complex had held an active shooter drill earlier in the day.
At the time of the incident, the Congress was not in session. According to the Senate Sergeant at Arms, the Senate convened today for a pro forma session, but remains adjourned until March 31.
The Capitol Visitor Center will remain closed until further notice.
