President Donald Trump revealed that he had told Defense Secretary Pete Hegseth to use inner cities as "training grounds" for war. In an unprecedented speech to top military brass on Tuesday, Trump said that American inner cities were "a big part of war now." "And this is going to be a major part for some of the people in this room. "And I told Pete, we should use some of these dangerous cities as training grounds for our military, national guard, but military, because we're going into Chicago very soon," he added. "You gotta do what you gotta do because we don't want our people hurt as they stand by."
