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 donât exist. Look at  this guy âs 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 donât exist. Look at  this guy âs 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."

Pyeongchang (South Korea) (AFP)  â American prodigy Nathan Chen  became the first figure skater to land six quads as  he  set an Olympic record in the free skate at the Pyeongchang Winter Olympics on Saturday.
The 18-year-old had bombed on Friday in a nervy short programme that left  him  languishing in 17th place going into the decisive day.
But  Chen  could yet grab a medal after a remarkable free skate that earned  him  215.08 points  one of the highest scores ever seen in the sport.
 Chen  did it on the back of six quads â four rotations in the air â breaking  his  own record of five set last year.
âI have been working on it for a while. Itâs never really fully come together â  Chen  said.

On Friday  Sen. Dianne Feinstein (D-CA) said she will introduce legislation that would raise the minimum age requirements for purchasing a rifle from a gun dealer.
 Feinstein 's declaration comes after 17 people were killed Marjory Stoneman Douglas High School in Parkland  Florida on Wednesday.
 Feinstein 's proposal received a mixed reaction.
I plan to introduce a bill to require ALL firearms purchases from gun dealers be restricted to individuals who are at least 21 years old. If you can’t buy a handgun or a bottle of beer  you shouldn’t be able to buy an AR-15. — Sen Dianne Feinstein (@SenFeinstein) February 17  2018
