Woodward also claimed Mattis said that Trump's intelligence was that of "a fifth- or sixth-grader". A new book says Prime Minister Narendra Modi wanted to have dinner with Donald Trump there last June.
Other Trump aides, including chief of staff John Kelly and Defense Secretary James Mattis, have denied quotes attributed to them in the book - quotes that ridicule Trump as "unhinged" and acting like a grade-school child.
The author said that several Trump officials were "not telling the truth" now that excerpts from the book are out, and that is understandable because everyone wants to stay in job. "I've seen this over the years, going back to the Nixon case".

According to the book, Trump told his national security aide that USA is losing in Afghanistan.
"We have reprinted six times for a total of seven to meet extraordinary demand - that will put one million books in print before we've even gone on sale", a Simon & Schuster spokesperson said to CNN "Reliable Sources" host Brian Stelter.
As Trump tries to take the upper hand on Woodward's choice not to name his sources in the book, Woodward stands firm on the quality of his reporting. Even approaching the debt ceiling can be harmful to the stock market and USA economic growth.
Woodward also said he wasn't lying, despite the president's accusations.
The looming release of Woodward's book, according to reports, has had the White House on edge for weeks.
