Author Michael Wolff said in an interview published Wednesday that his high-profile new book on the Trump White House sold a million copies in four days. 

“I’m going around saying, ‘It’s just a book,’ but it has become something so much larger,” Wolff told The New Yorker in an article published on Wednesday. 

"Fire and Fury: Inside the Trump White House" sent shockwaves through Washington last week after a series of controversial excerpts were published before the book's official release.

Bannon has received backlash from his past supporters and the president for the comments and has since resigned from his post at Breitbart News. 

Trump and the White House pushed back on the book, calling it "pathetic" and "full of mistakes." 

The White House also attempted to stop the book's publication with a cease-and-desist letter. 

Wolff's attorneys called the legal threats against the author “a gross violation of the First Amendment" on Monday.
