Pentagon rejects second request from D.C. mayor for National Guard help with migrants bused from Texas and Arizona

The Pentagon has rejected a second request from District of Columbia Mayor Muriel Bowser for the deployment of the D.C. National Guard to help receive and shelter migrants bused into the city from states like Texas and Arizona. 

In a letter to Bowser Monday, the Pentagon said the D.C. Guard is not trained or equipped to care for migrants, and the D.C. Armory is not air conditioned, making it unsuitable to accommodate anyone overnight, according to a copy of the letter reviewed by CBS News. 

The Department of Defense in its letter also acknowledged it is aware of concerns associated with uniformed military personnel in direct contact with migrants in a domestic operation.
