"You can not have, as President of the United States, someone who does not reflect the values that I believe Republicans treasure and Democrats treasure and independents treasure", Comey said.
Comey repeatedly pointed to how he feels like the president does not value the truth and how he has lied to the American people.
In a statement to The Associated Press, Lynch responds to criticism from Comey in his forthcoming book that, early in the email inquiry, she had instructed him to refer to it as a "matter" rather than an "investigation".More news: Trump warns Russian Federation on Syria: 'missiles 'will be coming'
If there was any chance that President Trump and James B. Comey could have avoided all-out war, it ended on Sunday night.
But the president also tweeted: "Attorney client privilege is now a thing of the past", referring to the Federal Bureau of Investigation raid last week on his personal attorney, Michael Cohen.
Trump has denied he asked Comey to stop investigating Flynn, who pleaded guilty to lying to FBI investigators about his contacts with Russia's ambassador to the United States.Trump has also used Twitter to call Comey a liar and called for his imprisonment.
Comey, who ran the Federal Bureau of Investigation for nearly four years, portrays the president in his book as a liar, dumb and rude, and he compares elements of Trump's behavior to that of a Mafia boss.
The president said he "stupidly" handled a probe into Trump's 2016 election rival Hillary Clinton and how she used a private email server during her time as secretary of state. She contested in the presidential election against Trump and lost.
Comey said he believed from the outset in the credibility of the source who wrote the dossier, former a British intelligence officer Christopher Steele. He didn't have any insight into the case, at least as far as I know, more than anybody reading the newspaper did, which was zero 'cause there were no leaks.More news: Assad supporters rally in Damascus after Western strikes
He said while he does not follow Trump on Twitter he was expecting a barrage of abuse over the candid interview. "And that's fine, so long as he's able to find that truth". Russian Federation has denied interfering in the election and Trump has denied any collusion or improper activity.
Comey said that it is "possible, but I don't know" whether Russian Federation had evidence to back up the allegations.
"I think it's possible". So I turn to them and I said, 'Someone put a lotta work into that.' And then I continued talking. Now on a publicity tour, Comey is deriding Trump at every turn, incurring even more of the president's all-caps Twitter rampages.
Comey told ABC he made what he thought was the appropriate decision and that a belief Clinton would win the vote for president was a factor.
The FBI director, who until his firing last May led an investigation into possible ties between Russian Federation and the Trump campaign, acknowledged that it was "stunning" to think that Russian Federation could have damaging information about an American president.More news: Greens announce plan to legalise cannabis
