Clash following the "Million MAGA March" on November 14, 2020 in Washington, DC.

Online forums popular with conservatives and far-right activists have been filled in recent days with threats and expectations of violence ahead of a planned protest in Washington on Wednesday to coincide with congressional certification of the election.

In anticipation of possible violence, Washington Mayor Muriel Bowser has asked residents to stay away from the downtown area where protesters will be marching. Every city police officer will be on duty, and the National Guard has been mobilized.
