Should emphasize that he says he has tapes…he also said that too about his Murdoch bio he did and threaten to release them if the NY Post(?) didn’t back off the stories on his personal life. They never came out, so it still a question of whether they exist. I think he has some tho, some of his quotes are too on point not to not come from a recording (ie the Ailes/Bannon dinner convo).
To the added caveat, some of Wolff’s reporting is being questioned, however Wolff does perface the entire book by saying that:
”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. Those 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 accounts and through sources I have come to trust, settled on a version of events I believe to be true.”
