It is subject of concern because his repetitions have become so much more frequent that it is that people find themselves around him saying: 'Oh my god, what are we going to do'.
Obscurity is a threat to Wolff no longer.
Trump responded immediately on Twitter bashing both the book's author Michael Wolff and former White House Strategist Steve Bannon. "It's all about him", Wolff told NBC's "Today" show. He called Wolff a "total loser" and claimed that Bannon "cried when he got fired and begged for his job".
A controversial book on Donald Trump's first year in office has sold out in US bookshops following its early release.
"That's the background to the perception and the understanding that will finally end... this presidency", he concluded. Full of lies, misrepresentations and sources that don't exist. "Look at this guy's past and watch what happens to him and Sloppy Steve!"
"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. I know from Bannon that he set up the whole thing. Whether he realised it was an interview or not. "But it certainly was not off the record".
He said his book was based on about 200 interviews.
Book Culture, an independent book seller in the Upper West Side neighbourhood, said on Friday morning four people had bought the book and it had about 160 copies available, with 150 copies available in its other store.
"Many, in Trumpian fashion, are baldly untrue", Wolff writes of some accounts. After a midnight release in Washington DC the book was an instant best seller. We're down to the benefit of the author of the book.
During the Friday edition of MSNBC's "Deadline: White House", host #Nicolle Wallace was joined by Kimberly Atkins of the Boston Globe to discuss Donald Trump's mental health. Book wholesale distributor Ingram Content Group also is out of stock, according to a spokeswoman.

President Trump should have never had Bannon on his team. The US President has also threatened lawsuits against Wolff and Bannon. Sometimes, he critiqued the media.
"Trump ended with: ".to President of the United States (on my first try). For chief economic adviser Gary Cohn, he was "dumb as s**t".
Mr Wolff said of the President's actions: "Where do I send the box of chocolates?"
Instead, he kept his attention fixed on a president whose opposition to his book has only heightened its profile.
