According to NBC News, Donald Trump’s chief of staff John Kelly may be out of his job soon as a result of a conflict with first lady Melania Trump and other people in the White House.

Nick Ayers, Vice President Mike Pence’s chief of staff, is being considered for the job among other candidates.

Two White House officials told NBC that Melania Trump had told the president earlier in 2018 that Kelly had repeatedly turned down requests to promote some of her aides, even as Kelly’s staff received promotions. Trump reportedly directed Kelly to approve Melania’s requests after learning of the disputes.

That report followed a slew of news that Homeland Security Secretary Kirstjen Nielsen may be on her way out as well.

The secretary’s potential forthcoming departure was reported a week after the midterm elections and days after the forced resignation of Attorney General Jeff Sessions.

But multiple outlets reported recently that Trump was planning a staff shakeup that would lead to both Nielsen and Kelly being removed.

“The Secretary is honored to lead the men and women of DHS and is committed to implementing the President’s security-focused agenda to protect Americans from all threats and will continue to do so,” DHS press secretary Tyler Houlton said in a statement Tuesday.

Nielsen had served in the Trump administration under chief of staff John Kelly before being confirmed to the Cabinet-level position in December.

Trump had praised Nielsen over the summer after she defended the administration’s border security goals amid a roiling controversy surrounding then-Attorney General Jeff Sessions’ “zero tolerance” immigration policy.

Homeland Security @SecNielsen did a fabulous job yesterday at the press conference explaining security at the border and for our country, while at the same time recommending changes to obsolete & nasty laws, which force family separation. We want “heart” and security in America!

But in the White House tell-all book “Fear,” Watergate reporter Bob Woodward wrote that Kelly had fought to convince Trump to confirm Nielsen.

“She’s terrible,” Trump reportedly told Kelly. “You’re the only one that thinks she’s any good. Maybe we’ll have to withdraw her nomination.” Trump ended up supporting Nielsen.
