The White House is on lockdown after shots appear to have been fired in the area.

The suspect approached a Secret Service checkpoint at 17th and E Streets and brandished a weapon. Uniformed agents "gave numerous verbal commands" to "stop and drop the firearm," the Secret Service said in a statement. When he "failed to comply," he was shot once by an agent and taken into custody.

The press corps has been told to shelter in place, then were moved to the basement after reports of shots fired at the corner of West Executive and Pennsylvania avenues.
