In his upcoming book, former FBI Director James Comey blasts President Donald Trump as an “unethical” pathological liar who is obsessed with personal loyalty, like a mob boss.

“ “Flashbacks to my earlier career as a prosecutor against the Mob. The silent circle of assent. The boss in complete control. The loyalty oaths. The us-versus-them worldview. The lying about all things, large and small, in service to some code of loyalty that put the organization above morality and above the truth.” ”

The bombshell tell-all book, “A Higher Loyalty: Truth, Lies and Leadership,” will be released Tuesday, but some media organizations, including the Washington Post, New York Times and Los Angeles Times, got hold of advance copies Thursday and published excerpts.

“What is happening now is not normal,” Comey writes. “It is not fake news. It is not okay,” he says, describing “the forest fire that is the Trump presidency.”

In the book, Comey — who Trump fired last May — offers a scathing look at the president, who Comey says is driven almost entirely by ego.

It includes a number of unflattering personal descriptions of Trump, from his “too long” tie to the “bright white half-moons under his eyes” on his otherwise orange face. Comey even notes the size of Trump’s hands, which he said were “smaller than mine, but did not seem unusually so.”

Comey describes how, in one meeting, Trump was seemed more concerned with “how they would spin” reports of Russian election-meddling, rather than how the problem could be avoided in the future, and how in another meeting Trump demanded his loyalty.

“I need loyalty. I expect loyalty,” Trump said, according to Comey. “I was determined not to give the president any hint of assent to this demand, so I gave silence instead,” he writes. “I stared at the soft white pouches under his expressionless blue eyes. I remember thinking in that moment that the president doesn’t understand the FBI’s role in American life.”

Comey also said Trump asked him to disprove the “pee tape” allegations that were in the controversial Steele dossier, saying that he was a germaphobe and would never allow people to urinate near him.
