Former White House Press Secretary Ari Fleischer said Thursday on "America's Newsroom" that it was "stunning" to see first lady Melania Trump call for the removal of a top White House official. 

Deputy national security adviser Mira Ricardel left the White House Wednesday, one day after Mrs. Trump's office took the extraordinary step of issuing a statement that called for her dismissal.

"It is the position of the Office of the First Lady that she no longer deserves the honor of serving in this White House," Stephanie Grisham, the first lady's spokeswoman, said in a statement.

Ricardel, who reportedly clashed with Mrs. Trump on a recent visit to Africa, was then reassigned within the administration.

Fleischer said most people don't pay attention to staff shakeups in the White House, but the perception of "chaos" negatively affects the administration. He said the situation involving Melania Trump and Ricardel is unlike anything he's ever seen in a White House.  

He said it's a "rule" among White House officials that you never "quarrel" with the first lady. 

"You should be smarter than that. ... The power of the first lady is the relationship with the first man. You tell the president 'there's something wrong here,' and the president takes action. What's stunning to me is action wasn't taken and so she had to issue a press statement. I've never seen that before," he said. 

Fleischer said it was "remarkable" to see Mrs. Trump effectively go around the president in public to accomplish the goal of Ricardel being ousted.
