Kelly started holding increasingly fewer senior staff meetings - once daily occurrences were whittled down to weekly gatherings - and began to exert less control over who talks to the President. Kelly's shifting accounts caused his credibility inside the West Wing to plummet, and it never truly recovered, according to officials.

Trump often vacillated between criticizing and praising Kelly, sometimes within minutes of each other.
