It's a short article, but this is the important part the lamestream leaves out.

Reading this causes me to wonder, if most of this is false or uncolaborated then why even write a book in the first place...unless of course, "it's Just Another Distraction".

Now, however, it looks like there could be much more to the story. Michael Wolff, the author of the title that set off the political fireworks, has admitted that he isn’t sure which parts of his own book are true — and that much of it may be exaggerated or blatantly false.

“Michael Wolff […] included a note at the start that casts significant doubt on the reliability of the specifics contained in the rest of its pages,” reported Business Insider reported. “Several of his sources, he says, were definitely lying to him, while some offered accounts that flatly contradicted those of others.”

Incredibly, the author of a book that is being treated as factual by much of the media admitted to “looseness with the truth,” and basically guessing about which accounts were accurate and which were invented out of thin air.

“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,” Wolff wrote in the book’s prologue.

This is the same info being reported by other news sources as well, even the Washington Post.
I read the authors notes on Amazons "Look Inside" and this last paragraph is there.
