I've now read Michael Wolff's Fire and Fury twice, and have seen nothing in the news since the book went to bed (last November) that has me doubting what's in it. Even if not a single thing in it is factually accurate, all of it rings true.
See, what Michael wrote is a portrait, not a photograph. And it's an artful one, since Michael is a helluva good writer. He's also the best media critic we've got. And Trump is, above all, a media character. So are, or were, all the many characters who surrounded Trump in the book's story of the administration's first eleven months. Now only three of those characters are left: Kellyanne Conway, John Kelly and the dual entity Steve Bannon calls Jarvanka.
