Michael Wolff, the author of "Fire and Fury: Inside the Trump White House," included a note at the start that casts significant doubt on the reliability of the specifics contained in the rest of its pages.His words, not mine.
Several of his sources, he says, were definitely lying to him, while some offered accounts that flatly contradicted those of others.
But some were nonetheless included in the vivid account of the West Wing's workings, in a process Wolff describes as "allowing the reader to judge" whether the sources' claims are true.
In other cases, the media columnist said, he did use his "journalistic judgment" and research to arrive at what he describes "a version of events I believe to be true."
Here is the relevant part of the note, from the 10th page of the book's prologue:
"Many of the accounts of what has happened in the Trump White House are in conflict with one another; many, in Trumpian fashion, are baldly untrue. These conflicts, and that looseness with the truth, if not with reality itself, are an elemental thread of the book.
"Sometimes I have let the players offer their versions, in turn allowing the reader to judge them. In other instances I have, through a consistency in the accounts and through sources I have come to trust, settled on a version of events I believe to be true."
