Author of 'Fire and Fury' says Trump "has less credibility than, perhaps, anyone who has ever walked on earth"

Trump is freaking out over Michael Wolff's new behind the scenes book about the Trumpian White House, Fire and Fury:

Wolff couldn't be more pleased by Trump's meltdown, and his attempt to stop the book's publication. "Where do I send the box of chocolates?" Wolff said in an interview on NBC's "Today":

From NBC:

Michael Wolff, the author of a new book that gives a behind-the-scenes account of the White House, defended his work Friday, insisting he spoke with President Donald Trump on the record and calling the commander in chief "a man who has less credibility than, perhaps, anyone who has ever walked on earth."

Wolff, in an exclusive interview on NBC's "Today," said that everyone he spoke to for the book, "Fire and Fury: Inside the Trump White House," described the president the same way.

"I will tell you the one description that everyone gave, everyone has in common: They all say he is like a child," Wolff explained. "And what they mean by that is, he has a need for immediate gratification. It is all about him."

Wolff added that "100 percent of the people around" Trump, "senior advisers, family members, every single one of them, questions his intelligence and fitness for office."

Fire and Fury is currently the best-selling book on Amazon.
