On Thursday, the U.S. Capitol Police ordered an evacuation of a House of Representatives office building near the Library of Congress after a suspicious vehicle was located near the Library of Congress.
Staff working inside the Cannon House Office Building were told to move to an adjacent building. Inside the library, staff were ordered to shelter in place, remain quiet and silence electronics.
"This is an active bomb threat investigation," the Capitol Police said on Twitter.
The Capitol Police asked anyone working in the Cannon congressional offices to leave and relocate to the neighboring Longworth building, while they had those in the Madison building bar themselves in their offices. The Jefferson Building, part of the Library of Congress, was also evacuated.
The House of Representatives and Senate are not currently in session.
"The USCP is responding to a suspicious vehicle near the Library of Congress," the Capitol Police wrote on Twitter. "Please stay away from this area."
