Calls are growing for President Trump to “clean house” at 1600 Pennsylvania Avenue, after a series of leaks aimed at embarrassing and undermining the president sprung from the White House this week.

A White House source estimates more than 60 percent of employees at the National Security Council are not Trump administration appointees, but career officials who were appointed to the White House from other agencies under the Obama administration.

The source said there are “whole departments” at the NSC with only one Trump appointee.

“I think the lesson here is that these things are going to continue to happen until the Trump White House does a serious housecleaning,” said Fred Fleitz, a former CIA and Bush administration official.
