A group of 25 House Democratic veterans sent a letter Thursday to President Trump, calling his remarks to military leaders earlier this week “un-American.”

The letter, authored by Rep. Pat Ryan (D-N.Y.) and signed by 24 other Democratic veterans, specifically criticized the president saying U.S. cities should be “training grounds” for the military Tuesday.

“They’re very unsafe places, and we’re going to straighten them out one by one,” Trump told more than 800 admirals and generals in Quantico, Va. “And this is going to be a major part for some of the people in this room. That’s a war, too. It’s a war from within.”
