(CNN) The White House, after a day of uncertainty, confirmed Wednesday that deputy national security adviser Mira Ricardel is leaving her position after first lady Melania Trump's office issued an unprecedented public statement calling for her ouster.

In a statement, press secretary Sarah Sanders said, "Mira Ricardel will continue to support the President as she departs the White House to transition to a new role within the Administration. The President is grateful for Ms. Ricardel's continued service to the American people and her steadfast pursuit of his national security priorities."

Multiple West Wing officials were unable to say where she is going -- because they do not know. Two officials raised the possibility that the White House has not determined where Ricardel will go yet.

An additional senior official confirmed today was Ricardel's last day at NSC, and she won't be finishing out the week in her old post.

Sanders declined to comment beyond her statement.
