Last week, President Trump incited what was essentially a white nationalist mob to storm the U.S. Capitol. Before the chaos, D.C. Mayor Muriel E. Bowser (D) had asked for a small deployment of D.C. National Guardsman, mainly to control traffic and monitor Metro stations. But when the violence erupted, she joined other local leaders — including Maryland Gov. Larry Hogan (R) and Virginia Gov. Ralph Northam (D) — in asking the Pentagon to deploy more forces, and to change the mission of the D.C. Guard. The Pentagon denied those requests at first, leading to a delay that may have lasted two hours (The exact timing is in dispute). District, Maryland and Virginia Guard troops eventually joined D.C. police officers and the Capitol police by nightfall and belatedly quelled the revolt.
