"The Woodward book is a Joke. Just another assault against me in a barrage of assaults using now disproven unnamed and anonymous sources " Trump said on Twitter
"Many have already come forward to say the quotes by them like the book are fiction. Democrats can t stand losing. I ll write the real book!" he added.
Since last week when several extracts were revealed of the book titled "Fear: Trump in the White House" which goes on sale this Tuesday the President has repeatedly blasted the journalist whose work he describes as a "scam " Efe news agency reported.
The book pictures the White House as a "Crazytown" ruled by the erratic behaviour of the President.
In one of the scenes described in the book soon after taking office Trump asked the Pentagon for a plan to launch a preventive military strike against North Korea while criticizing the high cost of protecting South Korea.
Defence Secretary James Mattis left a meeting with Trump about that request "exasperated and alarmed " and told people in the President s inner circle that he had "acted like - and had the understanding of - a fifth- or sixth-grader " according to Woodward.
Woodward whose 1974 reporting of the Watergate case in the Washington Post led to President Richard Nixon s resignation said he based his book "Fear" on interviews with witnesses to the hidden secrets of the White House who spoke on condition of anonymity.
