In those few months on the job, Ricardel generated a long list of enemies and developed a reputation for shouting at subordinates, plotting against White House officials she disliked and leaking stories about her administration opponents to the press.
Ricardel, who was hired in April by Bolton after he assumed the role of Trump's national security adviser, reportedly clashed with members of the first lady's staff over seating on a plane during Melania Trump's recent trip to Africa.
Officials told The Wall Street Journal that Ricardel was sacked and escorted from White House grounds, but a senior White House official told reporters that Ricardel was still inside her office this afternoon.
Ricardel also is known to have clashed with Defense Secretary Jim Mattis over Pentagon political appointee choices since early in his tenure.
A source familiar with Ms Ricardel's White House performance said the Deputy National Security Adviser also ran afoul of much of the NSC staff and "sort of alienated everyone" except for Mr Bolton, the veteran conservative foreign policy expert who has been Ms Ricardel's immediate superior.
"It is the position of the Office of the First Lady that [Ricardel] no longer deserves the honor of serving in this White House", the first lady's communications director Stephanie Grisham said in the statement, the Journal reported.
"I don't remember First Ladies being this involved publicly ever", she told Brooke Baldwin.
