The father-of-four has made many swipes about the President in the past, with one resulting in a bitter exchange with Piers Morgan.
The latter shared a picture of himself and Trump on Twitter, ahead of airing their interview together in January 2018.
Gary commented: “Congratulations, Tubs. Great scoop. Will it also be the 1st international TV interview from inside the bowels of a US President?”
Piers hit back, writing: “I don’t think you should be mocking anyone about bowels, Jugs.”
