President Trump's relationship with chief of staff John Kelly John Francis KellyMORE could be "irreparable," according to new report in Vanity Fair.

Trump has reportedly become frustrated with his chief of staff, four Republicans close to the White House told the publication.

“They’re fighting a lot,” one source said.

One person close to Kelly said: “He doesn’t love this job. He’s doing it as a duty for the country."

Trump has repeatedly praised Kelly.

This past weekend, Trump predicted Kelly would hold his post for his "seven remaining years" in office.

He told reporters at the White House that Kelly is "one of the best people" he's ever worked with.

"He's doing an incredible job," Trump said.

"And he told me for the last two months, he loves it more than anything he's ever done. He's a military man, but he loves doing this, which is chief of staff, more than anything he's ever done."

"He's doing a great job. He will be here — in my opinion — for the entire seven remaining years," he added.

Kelly assumed the role of chief of staff over the summer after former chief of staff Reince Priebus resigned in July.

Kelly has sought to instill discipline in the White House, and there have been fewer leaks in the months since his takeover.
