So many people have been leaving the White House, said President Donald Trump this month. "It's actually been really exciting and invigorating. I like chaos. It really is good." It is not clear whether he was joking - the remark was made during a light-hearted dinner speech - but, for Mr Trump's sake, one hopes he meant it.
The past one month has seen the resignation of his communications director Hope Hicks, the downgrading of his son-in-law Jared Kushner's security clearance, the resignation of his senior economic adviser Gary Cohn, the sacking-by-tweet of secretary of state Rex Tillerson, the escorting-out-of-the-building of his aide John McEntee and the firing of FBI deputy director Andrew McCabe. Now national security adviser H.R. McMaster has gone too.
