In Fire and Fury: Inside the Trump White House, Wolff continues to explore Trump's confounding, dualistic nature when it comes to the press, his impulsivity, and his alleged deepest secrets.
Wolff's book - which he says is based on interviews with Trump, his senior aides and others - also mentions that Trump eats food from McDonald's because he believes it to be safe from poison, and that his team did not believe he was capable of winning the election.
She also said the vast majority of interviews Wolff conducted with other White House officials were done at Bannon's request.
Mr Trump hit back yesterday, saying in a statement that when Mr Bannon was sacked, "he not only lost his job, he lost his mind".
They said in the letter, seen by Reuters, that Bannon had breached an agreement by communicating with Wolff about Trump, his family and the campaign and made disparaging remarks about Trump and his family. One former White House official said Wolff was known to camp out for hours in the West Wing lobby after meetings, sitting on a sofa as he waited to talk to staffers passing by.
Mr Trump strongly denies any collusion took place.
President Donald Trump threatened his former chief strategist Steve Bannon with legal action over "defamatory" statements about Trump's son and son-in-law over a meeting with Russians during the 2016 United States presidential campaign.
US President Donald Trump tried to counter one-two blows of betrayal and scandal Thursday, punching back at a bare-knuckle book that portrayed his White House as a fetid stew of backbiting, incompetence and dysfunction. Before Jan. 20, 2017, I knew that we were a great country; now I'm not so sure.
What did the lawyers say?
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.
But he has not refuted any of the statements that Mr. Bannon made.
Neither Wolff nor the publisher, Henry Holt and Co Inc, have yet responded.
The veracity of Wolff's writing has been called in to question many times in the past.
Mr Harder also briefly represented disgraced film producer Harvey Weinstein.
As a gossipy firsthand account of life in the White House, which sections are worthy of a cease-and-desist letter, and which of a full-on investigation? Reports over the past year indicated that the former Goldman Sachs COO has been close to leaving the Trump administration before, especially in the wake of Cohn's public admonishment of the president's response to racial violence in Charlottesville, Virginia.
Bannon has largely kept quiet since the controversy kicked up on Wednesday, but when asked about the controversy by a caller on his satellite radio show Wednesday night, Bannon offered only praise for the President. Mrs. Trump supported her husband's decision to run for President and in fact, encouraged him to do so. "She was confident he would win and was very happy when he did", she said on Wednesday.
"The security and integrity of the technology systems at the White House is a top priority for the Trump administration and therefore the use of all personal devices for both guests and staff will no longer be allowed in the West Wing".
