With Fire and Fury, Michael Wolff defined the first phase of the Trump administration; now, in SIEGE, he has written an equally essential and explosive book about a presidency that is under fire from almost every side.

Wolff interviewed 150 sources for the new book, including former senior officials and outside acquaintances who talk to Trump at night, Axios reported.

He did not sit down with the president himself, the news outlet noted.

“Fire and Fury: Inside the Trump White House” sent shockwaves across Washington in January 2018 and went on to sell more than 4 million copies, according to the publisher.

The book portrayed the Trump White House in chaos, including claims from Wolff that members of Trump’s staff questioned the president’s mental health and fitness for office.

Trump at the time criticized Wolff on Twitter, calling him the author of a “phony book!”

“Full of lies, misrepresentations and sources that don’t exist,” Trump wrote.

I authorized Zero access to White House (actually turned him down many times) for author of phony book! I never spoke to him for book. Full of lies, misrepresentations and sources that don’t exist. Look at this guy’s past and watch what happens to him and Sloppy Steve! — Donald J. Trump (@realDonaldTrump) January 4, 2018

“Siege: Trump Under Fire” is expected to be released June 4.
