The author of a book that is highly critical of Donald Trump's first year as US president said his revelations are likely to bring an end to Trump's time in the White House.
Michael Wolff told BBC radio that his conclusion in Fire and Fury: Inside the Trump White House that Trump is not fit to do the job was becoming a widespread view.
"I think one of the interesting effects of the book so far is a very clear emperor-has-no-clothes effect," Wolff said in an interview broadcast on Saturday.
"The story that I have told seems to present this presidency in such a way that it says he can't do his job," Wolff said.
"Suddenly everywhere people are going: 'Oh my God, it's true, he has no clothes'.
"That's the background to the perception and the understanding that will finally end ... this presidency."
Trump has dismissed the book as full of lies.
Wolff has previously said he based the book on more than 200 interviews, and had access to the White House and Trump himself.
He said he "absolutely" defended the contents of the book. He also said that he has audio recordings of interviews and extensive notes.
The book depicts a chaotic White House, a president who was ill-prepared to win the office in 2016, and Trump aides who scorned his abilities.
Publisher Henry Holt & Co moved up the release date of the book five days to Friday, maximising the publicity over the tome.
On its first day of release, bookstores in major cities including Washington DC, New York, and Los Angeles reported selling out of the initial order of the book.
Other shops in places like Oxford, Mississippi, and Shaker Heights, Ohio, also said that buyers quickly snatched up copies of their first batch.
Amazon already has the title on back order, with a ship date of two to four weeks.
