Interesting question.  The only thing that makes sense to me is that RT was set up to go so they could monitor him.  Perhaps he was dragging his ass about Hussein.  Perhaps he said or did something to betray Trump.  I never liked RT.  It was clear he is a NWO globalist traitor.    Same with McMaster.  I can only hope that Trump had McMaster closely watched so that Soros and others can be rolled up with him.
