There was one person, however, who McMaster couldn’t get rid of: Ezra Cohen-Watnick, the senior director for intelligence programs. McMaster tried to remove him in March, but President Trump, at the urging of Bannon and Jared Kushner, told McMaster that Cohen-Watnick was staying, as first reported by Politico. According to a senior White House official, the two men had a sit-down meeting the following week in which McMaster acknowledged that he hadn’t been able to do what he wanted to do, and that they would keep things as they are and “see how they go for a while.” That was over four months ago. That Cohen-Watnick, 31 years old and largely unknown before entering the administration, has become unfireable reveals how important he has become to the Trump White House, where loyalty is prized.
