>> Former FBI director James Comey called US president Donald Trump a dangerous, unfit leader. In exclusive interviews with ABC News and USA Today, Comey offered this view of the man who fired him.>> I don't think he's mentally unfit. I have read stuff about that he is, this bit about dementia and whatnot, I don't buy that.
He seems to be a person of above average intelligence. He follows, tracks the conversation all those kinds of things. That's not what I mean. I actually believe he's morally unfit to be president.>> Comey also told USA Today he believes that the president could be vulnerable to blackmail by Russia.
>> I don't know whether that's the business about the activity in a Moscow hotel room or finances or something else. But again, I don't wanna overstate it. I'm not saying it's likely. I'm saying to be honest with you, I have to say it's possible. And if you'd asked me two years ago, would I ever say that about an American president?
Of course not, that would never happen. But the honest answer is, it's possible.>> Comey was fired in May last year as the FBI was probing possible connections between Trump's 2016 campaign and alleged Russian interference in the US election. Russia denies meddling in the election, and Trump has called accusations of collusion a witch hunt.
Comey's comments come ahead of the release of his hotly anticipated memoir, A Higher Loyalty, Truth, Lies, and Leadership. And the White House launched a counterattack as soon as clips of the interviews began to air last week.>> This is nothing more than a poorly executed PR stunt by Comey, to desperately rehabilitate his tattered reputation, and enriches own bank account by peddling a book that belongs in the bargain bin of the fiction section.
>> The President on Monday, again, attacked Comey on Twitter saying quote, he committed many crimes. Trump provided no evidence to backup that claim. Trump's decision to fire Comey led the Justice Department to appoint special counsel Robert Mueller to take over the FBI probe into alleged Russian interference and collusion.
