Washington (CNN) President Donald Trump is not a complicated guy. He likes people who like him. He hates people who don't like him. And he trusts a very small group of people -- mostly members of his own family and a very few aides who have been with him from the start.

Which is why it makes total and complete sense that Trump picked Stephanie Grisham to be the new White House press secretary and communications director on Tuesday. Grisham has been a member of Trumpworld since the summer of 2015, when she signed on as traveling press secretary. She went on to become a close confidante of not just the President but, just as importantly, first lady Melania Trump -- for whom she has served as communications director. (Grisham is keeping that role even as she takes on a broader West Wing portfolio as well.)

Trump always favors those who have displayed the most loyalty to him but perhaps even more so at this moment -- when he is increasingly unhappy with the advice he has been getting from his various presidential advisers -- including acting chief of staff Mick Mulvaney
