Chris Wallace doesn't like the words chosen by the president to accurately criticize the sqaud and Elijah Cummings. Trump's selection of words is simply intolerable and offensive to sensitive Wallace.
Why don't you instead look into the substance of Trump's response to attacks initiated by the squad and Cummings against Trump and stop worrying about how Trump responded.
Wallace, good luck trying to curry favor with the leftist, Trump hating, mainstream media. Who knows, they may even offer you a slot over at CNN. That seems to your desired, natural habitat.
