For the first time since being fired as head of the FBI, James Comey sat down and gave a public interview about his time serving under Donald Trump, and the controversy that came with it. In no-holds-barred fashion, Comey didn't hold back.

Comey on Trump

It all started back in the 2016 presidential election when the FBI was investigation Hillary Clinton's use of a private email server during her time as Secretary of State.

The controversy became a top talking for Republicans, the right-wing media, and Donald Trump, which took a big hit when the FBI cleared Clinton of any wrongdoing. However, with pressure mounting on the issue, then FBI Director James Comey reopened the Clinton investigation just two weeks before Election Day, despite coming to the same conclusion. Fast forward to May 2017 and Comey was fired as head of the FBI by Trump, who accused him of pushing a "fake" Russian investigation against him.

This Tuesday, James Comey will be releasing his new book titled "A Higher Power" where he goes into detail about his exit from the FBI and his time with Donald Trump.

As seen during the April 15 edition of "20/20" on ABC, Comey spoke out on the issues at hand. "I liken President Trump in the book to a forest fire. Going to do tremendous damage. Going to damage those important norms," Comey told host George Stephanopoulos.

"He had impressively coiffed hair … it looks to be all his.

I confess I stared at it pretty closely," James Comey said of his first meeting with Trump, before noting, "His tie was too long as it always is...he looked slightly orange up close with small white half-moons under his eyes, which I assume are from tanning goggles."

"Pee tape" dossier

On the infamous "pee tape" dossier, Donald Trump reportedly asked James Comey, "Do I look like a guy who needs hookers?" " I don't know whether the current president of the United States was with prostitutes peeing on each other in Moscow in 2013," Comey told George Stephanopoulos, but noted that "It was coming from a credible source."

Comey's mob comparison

Not stopping there, the former FBI director went back in time when he was targeting the mafia, and even went as far as comparing Donald Trump to a mob boss.

"I think he’s morally unfit to be president," James Comey said, adding, "Very strange. And I don't do it lightly. And I'm not trying to, by that...suggest that Pres. Trump is out breaking legs and shaking down shopkeepers."
