Approximately 20,000 National Guard soldiers are set to be on the streets of Washington, D.C. by inauguration day. Many have been camped out inside the Capitol building, a sight that hasn't been seen since the Civil War. The hope is that the troops will deter any possible violence that may be aimed at Joe Biden’s inauguration. Robert Sanford, who was seen throwing a fire extinguisher at cops during the Jan. 6 riots, has been identified by his knit hat, which had “CFD” stitched into it. #InsideEdition
