Bob Woodward, the author of an explosive new portrayal of President Trump's White House, tells NPR that administration officials are denying his account out of "political necessity."
In his book Fear, which comes out Tuesday, Woodward describes Trump behaving erratically and impulsively, even on significant issues of national security, and insulting some of his senior officials.
President Trump has repeatedly denounced Woodward's book, calling the veteran journalist an "idiot" and his work a piece of "fiction."
