Protesters participating in a “Stop the Steal” rally in support of President Trump outside the U.S. Capitol breached a police security perimeter and stormed the U.S. Capitol building, forcing lawmakers to abandon the House floor.

Thousands of people who marched from the White House down Pennsylvania Avenue NW to Capitol Hill descended on the west side of the Capitol Wednesday afternoon. Police moved to evacuate surrounding Capitol office buildings, including the Cannon and Madison office buildings, and the Library of Congress.
