On January 6, 2021, the U.S. Capitol was attacked by a mob of supporters of Republican Pres. Donald Trump, disrupting a joint session of Congress convened to certify the results of the 2020 presidential election, which Trump lost to his Democratic opponent, Joe Biden. At a rally held near the White House, Trump repeated false claims about the election and encouraged the crowd to march to the Capitol.
The ensuing attack, during which rioters vandalized and looted the interior, resulted in property damage of approximately $1.5 million. The Capitol was cleared of rioters about four hours after they first entered the building, and Congress resumed its tabulation of electoral votes, certifying Biden as the winner.
