Trump himself, in a post to Twitter Thursday night, said he never spoke to Wolff for the book, which the president said was "full of lies", and did not authorize White House access for the author.

The publisher, Henry Holt, responded by moving up the publication date of "Fire and Fury: Inside the Trump White House", by journalist Michael Wolff, to Friday. Donald (Don) John TrumpTrump files paperwork to transfer businesses MORE as "treasonous", alongside other salacious quotes from current and former Trump staffers.

The diplomats added that U.S. officials told U.N. officials in the last two days that President Trump is considering totally cutting the part of the funding which was frozen, and is even considering cutting up to $180 million, which amounts to half of the U.S. funding to UNRWA.

The book that created a rift between President Trump and his former campaign chief executive and adviser Steve Bannon hit the shelves Friday morning, ahead of the original Tuesday release date, despite the president's threat to block its publication.

Stay tuned tomorrow, when the administration uses Air Force One to fly over Wolff's house with the message, "Nobody buy this guy's book on Amazon".

Wolff's track record for accuracy has been disputed, and there have already been a few factual issues identified in the book.

"A non-disclosure or non-disparagement contract only binds the parties to the agreement, not others who obtain the information", said Jonathan Adler, a professor of law at Case Western Reserve University in Cleveland. This isn't his first book; he also published a controversial profile on Rupert Murdoch, and his award-winning Vanity Fair columns are known for revealing triumphs and secrets of powerful individuals.

"It used to be inside of 30 minutes he'd repeat, word-for-word and expression-for-expression, the same three stories - now it was within 10 minutes".

Meanwhile, the Department of Homeland Security was widely reported on Friday to have asked for $18bn (£13.3bn) to complete a section of Mr Trump's much-vaunted border wall with Mexico - though it is unclear if this will be discussed in the latest round of budget talks.

"Steve Bannon has nothing to do with me or my presidency", Trump said in a statement later on Wednesday.

Axios reported that Wolff had hours of taped interviews, including some with Bannon and former White House deputy chief of staff Katie Walsh.

"I think that's well recognised".

"I got as far as the Fourth Amendment before his finger is pulling down on his lip and his eyes are rolling back in his head", Wolff writes of Nunberg's recollection. "This book is about Donald Trump". During a press conference on Thursday, White House press secretary Sarah Huckabee Sanders repeatedly denied numerous claims in the book.

"We're concerned about the public health risk posed by him, by his mental instability", she said. (He also tweeted about the unemployment rate and an ABC News reporter suspended by the network over a reporting error.) Tweeters were quick to mock him. Wolff says that much of the first lady's life before the presidency was "entirely focused on her young son", however. But the fact that it's plausible that such craziness happened should be concerning, he said. "It's disgraceful and laughable", Sanders said.
