'You don't need a book to know Trump behaves like a child': MSNBC guest has the last word on Trump-bashing 'Fire and Fury'

During an MSNBC panel discussion on author Michael Wolff's blockbuster 'Fire and Fury,' MSNBC contributor and host of WHYY's 'The Remix,' James Peterson, said he saw nothing new in the book that has the country in an uproar, adding he already knew President Donald Trump "acts like a child."

Speaking with host Alex Witt, commentator Peterson was quite matter-of-fact about what the book confirmed to anyone who has followed the blustery businessman from Trump Tower to the White House. But not until after former Obama speechwriter David Litt got in his shots.

"President Trump's response to a book that suggests he is a petulant, self obsessed child-like person and he behaves like a petulant, self-obsessed child-like person," Litt said.

"This is not what a very stable genius would do in this situation," he quipped, adding, "But I don't think any of us are surprised by that."

Peterson then jumped in to deliver what, for many, was their takeaway from the revelations in the book.

"I think the book is a bombshell without question, Alex," he began. "But it's more of a bombshell in terms of confirmation as opposed to any revelation. You don't need 'Fire and Fury' to understand that this president behaves like a child at times -- all you have to do is follow his Twitter feed."

'"You don't need to understand that this White House has been chaotic from a book, you can see the chaotic nature of this White House by the way it's prosecuted its agenda over the course of the last year," Peterson continued. "So the evidentiary piece of the book is to me less important. The American people can look at what's going on, can look at the president's Twitter feed, can look at the ways in which policy has been enacted by this administration, by the ways in which people have been fired and the sort of revolving door of the administrative staff itself. There's evidence in the public sphere that this book might confirm that I think makes it believable."
