The policy requires staffers to leave their cellphones — government-issued or personal — in their offices or in lockers near the entrances to the West Wing before entering the Situation Room.

Previously, they were allowed to leave cellphones in lockers outside the room.

CNN said the White House did not immediately respond to a request for comment. The Hill has also reached out for comment.

Manigault Newman released the recording last month. She was fired in 2017.

"Yes I recorded myself and I have no regret about it," Manigault Newman told NBC's "Meet the Press" when the recording aired.

Conservatives have called into question the legality of Manigault Newman's actions.

"Secretly recording conversations in the Situation Room isn't just wildly inappropriate, it's a threat to our national security. If she broke federal law, she should be prosecuted," Republican National Committee Chairwoman Ronna Romney McDaniel tweeted after Omarosa's admission.

Journalists, national security experts and former White House staffers have noted that phones aren't allowed in the Situation Room for security concerns. However, it is unclear if Manigault Newman's actions qualify as a criminal offense.
