Comey is embarking on a publicity rollout of his book, "A Higher Loyalty", which offers his version of the highly controversial events surrounding his firing by Trump and the Russian Federation and Hillary Clinton email investigations.
Top White House aides are pushing back on a new book from former Federal Bureau of Investigation director James Comey that depicts President Donald Trump as unethical and "untethered to the truth".
President Donald Trump says former FBI Director James Comey is an "untruthful slime ball" who should be prosecuted for leaking classified information.
This is not the first time that the White House has worked to undercut an unflattering book.
The White House has unleashed a blistering critique of former FBI Director James Comey as he begins promoting his memoir.
Comey testified before Congress Trump's quest for loyalty made him uncomfortable.
It is rare for a sitting USA president to comment on ongoing litigation, much less ask for critics to be prosecuted.
"I took it as a very disturbing thing, very concerning", he declared under oath.
Calling Comey a "disgraced partisan hack", White House spokeswoman Sarah Sanders told reporters that the American people would be able to see through the "lies" in Comey's book, which offers a scathing assessment of President Trump.
Comey's no holds barred account of his meetings with Trump before he was sacked at times appears mean spirited, but also conveys a sense of disbelief about the 45th president's behavior.
The US president lives in "a cocoon of alternative reality" that he tried to pull others around him into, Comey adds.
In the forthcoming book, Comey compares Trump to a mafia don and calls his leadership of the country "ego driven and about personal loyalty".
Comey even describes Trump as a mob boss.running the oval office like a Godfather!
Comey also claims that the USA 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.
Puzzled readers turned to their dictionaries after Trump wrote on Twitter that Comey was "a weak and untruthful slime ball who was, as time has proven, a bad Director of the Federal Bureau of Investigation".
