Police used tear gas and stun grenades to clear pro-Trump protesters outside the Federal Capitol before 7 p.m., when a curfew should begin in Washington.
Police put on gas masks as they emptied protesters from Capitol grounds. In earlier times, there were violent clashes between police and protesters.
Hours earlier, dozens of supporters of President Donald Trump crossed the security perimeter and entered the Capitol as Congress met to confirm Democratic presidential victory over Joe Biden. They were seen fighting with agents both inside and outside the building.
