Former FBI Director James Comey's first sit-down interview since he was fired by President Trump just aired tonight on ABC.

He talked a lot about President Trump and the Hillary Clinton email investigation.

Here are some of the things he said:

On Trump's hair: "He had-- impressively coifed hair, it looks to be all his. I confess, I stared at it pretty closely and my reaction was, 'It must take a heck of a lot of time in the morning, but it's impressively coifed.'"

On Trump's presidency: "I think he's morally unfit to be president."

On whether Trump should be impeached: "I hope not because I think impeaching and removing Donald Trump from office would let the American people off the hook, and have something happen indirectly, that I believe they're duty bound to do directly."

On Trump wanting loyalty: Comey claimed Trump told him, "I expect loyalty, I need loyalty."

On whether Trump obstructed justice: Comey said there is "certainly some evidence of obstruction of justice."

On being fired: "I thought it's crazy to fire me."

On whether Russia has compromising information on Trump: "I think it's possible. I don't know. These are more words I never thought I'd utter about a President of the United States, but it's possible."
