The author behind a recent anti-Trump exposé admits in the book’s prologue that vast sections of his work were likely untrue, saying several of his sources “lied to him” and insider accounts “flatly contradicted those of others.”

According to Business Insider, Michael Wolff admits that different accounts of the early days of the Trump Presidency described in “Fire and Fury: Inside the Trump White House” were false, urging readers to “make up their own minds.”

In the book’s prologue, the author writes, “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,” he adds. “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.”

“The book itself, reviewed by Business Insider from a copy acquired prior to its Friday publication, is not always clear about what level of confidence the author has in any particular assertion,” writes the article.
