Keith Schiller was never just a bodyguard. He's worked for Trump since 1999 and in nearly 20 years has become one of a handful of people outside of Trump's immediate family that the president truly trusts.
Now he's leaving the White House, and Trump's friends worry about the effect Schiller's absence will have on the president's psyche. Trump believes Schiller "tells him the truth because the only dog he has in the fight is the boss," a friend told Axios. Trump confides in Schiller and asks his advice about everything, including policy.
