Melania Trump issued an unusual public statement demanding that Ricardel leave the White House after clashes between National Security Adviser John Bolton's top deputy and the first lady's staff over her trip to Africa last month.
The statement made no mention of Melania but said, 'The President is grateful for Ms. Ricardel's continued service to the American people and her steadfast pursuit of his national security priorities'.
Fleischer said most people don't pay attention to staff shakeups in the White House, but the perception of "chaos" negatively affects the administration.
Ms Ricardel's ouster comes as Mr Trump considers a range of changes to his administration. National Security Advisor John Bolton became aware of Mrs. Trump's complaints, but Ricardel kept her office until this week, when the FLOTUS office publically called for her removal. He is traveling in Asia this week alongside Vice President Mike Pence. "I've never seen that before", he said. Sanders did not specify the aide's new role.
Maddow updated her viewers that was announced that Ricardel would be leaving the White House.
There are reports Trump is also about to fire Homeland Security Secretary Kirstjen Nielsen.
Trump has been in a funk since last week's midterms which saw the Democrats seize control of the House of Representatives, ending the Republicans' dominance of both chambers of Congress.
Pressure is mounting from the probe, as the special counsel Robert Mueller digs ever more deeply into the president's inner circle. Trump also replaced his attorney general Jeff Sessions last week immediately after heavy losses during the mid-term elections.
The Department of Justice ruled on Wednesday that Mr Whitaker's appointment is in fact constitutional, but this will do little to calm claims that Trump's real goal is to defang the Russian Federation probe, which he describes as "a witch hunt".
However an ex-colleague described her as someone who doesn't "suffer fools" and who lacked the skills to tactfully navigate the internal politics of the White House.
