Mira Ricardel barely lasted seven months as deputy national security adviser before First Lady Melania Trump issued an unprecedented call for her dismissal and President Donald Trump moved to fire her. No replacement was named.
Two presidential aides said Trump was considering forcing out deputy national security adviser Mira Ricardel, but as of Tuesday afternoon, the adviser remained in her West Wing office.
The deputy NSA's ouster was called for by Melania on Tuesday, following which Trump had made a decision to relieve Ricardel from her duties, a White House official confirmed.
According to USA media reports earlier this week, Mrs Trump and Mrs Ricardel quarrelled over seating arrangements on her plane.
While the conflict with the first lady is getting the most attention, Ricardel has also clashed with Defense Secretary Jim Mattis since Trump's transition, according to an October report from the Washington Post.
Ricardel is a former Commerce Department official hand-picked by Donald Trump's national security adviser, John Bolton, to serve as his deputy, Reuters reports. Citing people familiar with the row, the outlet claims that Ricardel clashed with them over seat distribution on the plane.
But Ms Sanders didn't say what Ms Ricardel's new job would be, and didn't respond to follow-up questions.
These officials said Mrs. Trump's statement blindsided many people on Trump's staff and was unfair in general. He is travelling in Asia this week alongside U.S. Vice-President Mike Pence.
Reports surfaced late on Monday that Trump was preparing to remove Nielsen, a close ally of Kelly's with whom the president has grown frustrated over immigration enforcement.
Attorney General Jeff Sessions was forced out by Trump last week just hours after the results came in from the November 6 elections, which handed majority control of the House of Representatives to Democrats.
On Tuesday, Melania Trump sought her removal.
In the months since Ricardel's arrival at the NSC, White House sources have repeatedly leaking stories to the press saying that Ricardel and Bolton were spreading rumors about Mattis' imminent departure in an effort to pressure the Pentagon chief to leave.
While the Republicans held their Senate majority, the Democratic win means the president will for the first time face an opposition that has teeth.
Democrats vow to use their control of powerful oversight committees to go after Trump's nebulous personal finances and to protect an explosive probe into whether his 2016 election campaign colluded with Russian agents.
