So Michael Wolff wrote a book about Donald Trump. Perhaps you've heard about it?

The internet spent a few days pointing and laughing at the more extraordinary claims about Trump's behavior (including some the book didn't actually make), and then settled down to the serious business of figuring out which of them were true.

The consensus here in Washington is that Mr. Wolff has perhaps been a little too credulous with his sources, particularly with Steve Bannon, who has since recanted. But beneath that is the feeling that while many of the specifics are in question, the underlying picture resonates with those who deal with the White House.
