Pentagon officials express concern as Trump threatens to use military to "dominate" protestors

But some Pentagon officials are deeply wary, several defense officials tell CNN. They have tried to respond by making a strong case that the situation does not yet call for deploying active duty troops unless state governors make a clear argument such forces are needed.

“There is an intense desire for local law enforcement to be in charge,” a defense official said, alluding to the laws that forbid the military from performing law enforcement roles inside the United States.

There is also discomfort with the civil order mission among some National Guard troops — more of whom are now mobilized inside the US than at any previous time in history.

“I believe that we in America should not get used to or accept uniformed service members of any variety having to be put in a position where they are having to secure people inside the United States of America,” Army Maj. Gen. Thomas Carden, the Adjutant General of the Georgia National Guard, told reporters Sunday. He added that although “while we are glad to do it and honored to do it, this is a sign of the times that we need to do better as a country.”
