Buckle up, Michael Wolff has a new book and you can be sure Donald Trump won’t like what it has to say. The book, “Siege: Trump Under Fire” comes out next Tuesday. But strategic leaks to help sell the book have already begun.

The book’s official description says it “reveals an administration that is perpetually beleaguered by investigations and a president who is increasingly volatile, erratic, and exposed.”

The Guardian reports that they obtained an advance copy of the book and that one of the revelations points to how the Mueller report could have ended differently saying:

Special counsel Robert Mueller drew up a three-count obstruction of justice indictment against Donald Trump before deciding to shelve it – an explosive claim which a spokesman for Mueller flatly denied.

The Guardian points out that Wolff says his findings were “based on internal documents given to me by sources close to the Office of the Special Counsel.”

Wolff previously wrote, “Fire and Fury, Inside The Trump White House,” which became a New York Times bestseller.
