The well-documented chaos in the White House reflects both the difficulty faced by anyone who seeks to impose discipline on the President, and Trump's own inability to cope with people he cannot bully. The four most competent people in his circle, Secretary of State Rex Tillerson, Defense Secretary James Mattis, economic adviser Gary Cohn and Chief of Staff John Kelly appear to be fighting against Trump's chaos, for the good of the country.

Remarkably, we are not hearing senators rushing to contradict Corker's claim that his fellow Republicans are concerned about Trump's mental state. This indicates that while they may fear Trump's wrath, they are also worried.

The most arresting inside evaluation of Trump's condition came from his longtime friend and fellow real estate mogul Tom Barrack, who told The Washington Post he has been "shocked" and "stunned" by Trump's recent behavior, even as he says he still believes the President is "better than this." In the same interview, Barrack told the Post he has been able to be Trump's friend, and to disagree with him, because "I've never needed anything from him."
