Trump has decried the instant best-seller as "phony" and "full of lies".
Michael Wolff's book "Fire and Fury: Inside the Trump White House" went on sale on Friday, its release pulled forward after published excerpts this week set off a political firestorm, threats of legal action and an effort to halt publication.
Wolff said the cease-and-desist letter Trump's lawyers sent Wolff and his publisher to prevent him from releasing the book has only helped to generate massive interest.
The 64-year-old author appeared on US television to discuss his book, and said he had held extensive conversations with Mr Trump.
Those anecdotes show how unprepared Trump is for the presidency, and how he ignores or disregards advice and follows his instincts wherever they lead - even when he contradicts himself.
Trump tweeted Friday: "The Mercer Family recently dumped the leaker known as Sloppy Steve Bannon". In addition to that, he lashed out at Bannon, calling him "Sloppy Steve" for giving an interview to Wolff.
Trump also took another shot at his favorite target, Hillary Clinton, in a series of tweets early Saturday. "It's all about him".
Mr Wolff has said he wrote the book after conducting about 200 interviews.
What did the short-fingered vulgarian say to make her feel better?
Secretary of State Rex Tillerson, who is one among top administration officials to have spent the most time with Wolff, however ridiculed any negative impression about Trumps mental health.
Wolff's claims concern various aspects of life at Trump's White House, including separate sleeping arrangements, his confidants, daily habits as well as the atmosphere during the presidential campaign and on election day.
The tweet burst erupted in the morning from Camp David on a day the president is meeting with top Republicans in Congress to work out a legislative agenda for 2018.
"I want to get an insider's opinion into what was going inside this White House", John Cota explained when asked about his interest in the book.
"We will have 10 copies after Jan. 20", she said. He also says he never spoke with the book's author.
Trump responded immediately on Twitter bashing both the book's author Michael Wolff and former White House Strategist Steve Bannon.
