Citing three anonymous sources, the newspaper said Kelly was calm, but "later told other White House staff members that he had never been spoken to like that during 35 years of serving his country".
Several sources say President Donald Trump's frustration with some of his aides and the progress of his presidency is growing. According to the latest Times report, coauthored by Trump monitor nonpareil Maggie Haberman, Kelly has tried to take a light touch with the President, but has not been able to entirely maintain Trump's enthusiasm for him.
White House Press Secretary Sarah Huckabee Sanders told CNN that it was "not true" that he was leaving around the end of September. "Now Mr. Kelly has thinned out his package of printouts so much that Mr. Trump plaintively asked a friend recently where The Daily Caller and Breitbart were".
But the government's largely well-received handling of the storm has not soothed Trump's own frustrations, according to those who speak with him regularly. "He's turning on people that are very close to him".
In the five weeks since John Kelly became Donald Trump's Chief of Staff, the retired Marine Corps General has ejected unstable staffers, imposed new controls on who can meet with the President, and restricted the news the President consumes. It may not be long before POTUS decides he'd rather have familiar faces around him again and a chaotic West Wing than be "managed" by Kelly, cloistered away in the Oval Office by himself.
While strategist Steve Bannon, who repeatedly preached to Trump the importance of fulfilling his campaign promises, left the White House shortly after Kelly's arrival, the president has made aggressive moves on some of the issues Bannon promoted.
"General John Kelly is doing a great job as Chief of Staff", Trump said on Twitter. "I think it was purposefully done this way, to bring Bannon in, let him see the inner workings of the beast, and see who the beasts actually are, and then come out, and then wage war against them on the outside".
