Acting Defense Secretary Christopher Miller on Monday approved a request from the mayor of Washington to deploy DC National Guard forces to the city to support local authorities during pro-Trump demonstrations scheduled in the city this week, a defense official told CNN.

Mayor Muriel Bowser made the request Thursday in a letter addressed to Maj. Gen. William J. Walker, the commanding general of the DC National Guard, in which she referenced protests in the city in November and December that “resulted in a large influx of participants, violence and criminal activity.”

“No DCNG personnel shall be armed during this mission, and at no time, will DCNG personnel or assets be engaged in domestic surveillance, searches, or seizures of US persons,” Bowser, a Democrat, wrote in the letter.
