Comey also claims that the U.S. president is obsessed with the alleged existence of a video showing Russian prostitutes said to be hired by Trump urinating on each other in a Moscow hotel room.
"James Comey proved himself as the author of the leaks and a liar". In previous testimony, however, he said he never authorized an FBI subordinate to leak information about investigations of Trump or Clinton.
White House aides said Sanders' unusual barrage at Comey reflected Trump's anger and that Trump was pleased by her performance. For the unitiated, that's about a tape allegedly recorded by Russian intel, of Donald Trump in a Moscow hotel room with prostitutes peeing on each other. The allegations left Trump fuming.
Trump wrote on Twitter Friday: "He is a weak and unethical slimeball who was, as time has proven, a bad Director of the Federal Bureau of Investigation". His handling of the Crooked Hillary Clinton case, and the events surrounding it, will go down as one of the worst "botch jobs" of history. Comey's book is already at number 11 on Amazon's bestsellers of 2018 - Michael Wolff's Fire and Fury, another Trump presidency-focused book, is now at number one.
Demand for Comey's stories about his interactions with Trump has been at a high since Comey was sacked by the president last May.More news: Suspect in shooting of Cape Cod cop Sean Gannon faces arraignment

News organizations including AFP obtained copies of the manuscript, in which Comey portrays Trump as an egomaniac - "unethical, and untethered to truth and institutional values".
In attempt to blunt the impact of the new book, the Republican National Committee is waging a widespread campaign to undercut Comey's credibility, including a new website that dubs the former Federal Bureau of Investigation chief as "Lyin' Comey".
Meetings with Trump gave Comey "flashbacks to my earlier career as a prosecutor against the Mob", he says.
In the ABC segment that aired Friday, Stephanopoulos also asked Comey if he had disclosed to Trump the source of funding of the dossier, compiled by Christopher Steele, a former British intelligence officer. The book adheres closely to Comey's public testimony and written statements about his contacts with Trump and his own growing concern about Trump's integrity.
"The American people see right through the blatant lies of a self admitted leaker", White House Press Secretary Sarah Huckabee Sanders said of former FBI Director James Comey.
The 6-foot-8 Comey describes Trump as shorter than he expected with a "too long" tie and "bright white half-moons" under his eyes that he suggests came from tanning goggles. "It was my great honor to fire James Comey!".
