Washington: Deputy National Security Adviser Mira Ricardel is leaving the White House, one day after first lady Melania Trump's office issued an extraordinary statement calling for her dismissal.

No replacement was named. Aides said Ricardel clashed with the first lady's staff over her visit to Africa last month.

Ricardel threatened to withhold National Security Council resources for the trip unless she or another NSC staffer was included in the first lady's entourage, according to a person familiar with the matter.

Melania Trump and Ricardel have never met, the person added.
