Sims depicts Trump as deeply suspicious of his own staff. He recalls a private huddle in which he and Keith Schiller, the president’s longtime bodyguard and confidant, helped Trump draw up an enemies list with a Sharpie on White House stationery. “We’re going to get rid of all the snakes, even the bottom-feeders,” Trump told them.

White House Chief of Staff John F. Kelly told the staff that he viewed his job as serving the “country first, POTUS second,” which Sims interpreted as potentially hostile to Trump’s agenda.

Sims recounts that Kelly once confided to him in a moment of exasperation: “This is the worst [expletive] job I’ve ever had. People apparently think that I care when they write that I might be fired. If that ever happened, it would be the best day I’ve had since I walked into this place.”
