'Fire and Fury' author disputes Trump claim he had 'zero access'

Michael Wolff, author of "Fire and Fury: Inside the Trump White House," is disputing President TrumpDonald John TrumpHouse Democrat slams Donald Trump Jr. for ‘serious case of amnesia’ after testimony Skier Lindsey Vonn: I don’t want to represent Trump at Olympics Poll: 4 in 10 Republicans think senior Trump advisers had improper dealings with Russia MORE's claim that he gave Wolff "zero access" to the White House for the book.

"I absolutely spoke to the president... it certainly was not off the record," Wolff said on NBC's "Today Show" Friday morning, just hours after the midnight release of the book.

"My window into Donald Trump is pretty significant," he added. "I work like every journalist works. I have recordings. I have notes. I am certainly and absolutely in every way comfortable with what I have reported."

Wolff also took a jab at Trump for his criticism, saying: "My credibility is being questioned by a man who has less credibility than anyone who walks on Earth."

His comments come after Trump railed against the book on Twitter late Thursday.

"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!" Trump tweeted.

The White House also said earlier this week that Trump never sat down with Wolff. 

White House press secretary Sarah Huckabee Sanders told reporters on Wednesday that the only direct interaction between Wolff and Trump was a five- to seven-minute phone call shortly after the inauguration.

The Trump administration has hammered Wolff and his publishers over the book, which depicts chaotic early days in the Trump White House.

In his interview with "Today" Friday morning, Wolff said his book details aides transitioning from viewing Trump as an "interesting, unique character" to reaching "the conclusion that he cannot do this job."

"This man does not read. Does not listen. He's like a pinball, just shooting off the sides," he said of Trump.
