Trump has so far refused to concede to Biden and claims without evidence that he was cheated by widespread election fraud.

In the morning, Trump's motorcade drove through the crowds on the way to his golf course in Sterling, Virginia.

Demonstrators cheered as the president waved from inside the presidential limousine.

Among the protesters were members of the far-right Proud Boys group, clad in black with some wearing helmets and ballistic vests.

The Trump supporters – many not wearing masks – marched from Freedom Plaza near the White House to the U.S. Supreme Court.
