Tom Popinsky, a professor of government at Cornell University, says the president turning on one of his favourite appointments is not out of the question.

“You need to understand this in terms of President Trump imagining he’s running The Apprentice reality television show again, in which he gets the chance to make big news by saying he’s firing somebody,” Professor Popinsky said.

“I think the argument for this happening is that he would interpret this as a TV ratings bump. He would get a ratings bump for firing Hegseth.”
