Input: In a full-throated denunciation of the work   Trump  tweeted Thursday night that  he  had authorized "zero access to White House (actually turned  him  down many times) for author of phony book!"
"I never spoke to  him  for book  " Trump  wrote. "Full of lies  misrepresentations and sources that donât exist. Look at  this guy âs past and watch what happens to  him  and Sloppy Steve [Bannon]!"
In an earlier statement  Trump  had blasted Bannon   his  former White House strategist and a major on-the-record source for the book  saying  he  had "lost  his  mind."
As for  Trump 's charges that the book is not credible  Wolff responded: "My credibility is being question by a man who has less credibility than perhaps anyone who has walked the earth."
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 donât exist. Look at  this guy âs past and watch what happens to  him  and Sloppy Steve!  â Donald J. Trump (@realDonaldTrump) January 5  2018
 On  Trump 's charge that  he  had not authorized Wolff to spend time at the White House to report on the book  the author said  "What was I doing there if  he  didn't want me to be there?"
Asked  his  reaction to the president's effort to block the publication  Wolff said it only served to boost sales: "Where do I send the box of chocolates?"
Wolff said  Trump  is "not only helping me sell books  but helping me prove the point of the book."
He said he not only spoke to  Trump   but also to top White House officials who met with the president daily  sometimes on a minute-by-minute basis.
Wolff said he had only one question in mind in writing the book: "What is it like to work for  Donald Trump   how can you work for  Donald Trump   and how do you feel having worked for  Donald Trump ?"
In the book   he  paints a portrait of a disorganized White House run by a mercurial  uninformed president who is constantly minded by other to keep  him  on track and focused.
Wolff said his sources repeatedly referred to  Trump  as "like a child" who "has a need for immediate gratification." Wolff said.
Even this week  on the question of sending a cease-and-desist letter to the book publishers   Trump  brushed aside in-house advice that  he  shouldn't do it  Wolff said. " He  just insists â  he  has to be satisfied in the moment."
