Vanity Fair’s Gabriel Sherman reported that Ivanka Trump had been put in charge of finding a replacement for John Kelly, a strong indication that the White House Chief of Staff may soon feel the full weight of the Trump Bus as it rolls over his well-decorated chest.

“Ivanka is the most worried about it. She’s trying to figure who replaces Kelly,” someone who has spoken with the president’s daughter told Sherman.

According to Sherman, Kelly’s days as Trump’s chief of staff “may finally have gone past the point of no return.”

It would seem that being seen as the “grown-up in the room” is a firing offense at the Trump White House.

Kelly recently came under fire by the president’s defenders after he told lawmakers that Trump had “evolved” on the issue of a border wall.

“The more Kelly plays up that he’s being the adult in the room—that it’s basically combat duty and he’s serving the country—that kind of thing drives Trump nuts,” one Republican close to the White House explained.

According to Sherman, the President disparaged Kelly’s mental status in a recent comment.

“I’ve got another nut job here who thinks he’s running things,” Trump reportedly said.

Kelly allegedly has said he hopes to serve longer than Reince Preibus did as Chief of Staff, a low bar indeed to measure one’s career against.
