Toobin was asked during a segment on the network whether he thinks Comey's claims that Trump asked him to let the investigation into former national security adviser Michael Flynn go was evidence of possible obstruction of justice.

"I don't think it's evidence of obstruction of justice. I think it is obstruction of justice," Toobin said.

"There's just no other way to describe what the president was doing, if Comey's account of the conversation is correct. He is trying to stop an investigation of a subordinate in the Russia investigation."

Toobin said he believes it was a "crime committed in the Oval Office."

"I just think it's a completely devastating account of the president's behavior," Toobin said.

Comey spoke during an interview with ABC News that aired Sunday night meant to promote his new book, "A Higher Loyalty."

During the interview, Comey said there is "certainly some evidence" that Trump obstructed justice when asked about the investigation into Flynn.

“It would depend and — and I'm just a witness in this case, not the investigator or prosecutor, it would depend upon other things that reflected on his intent,” Comey said.

The remarks came in response to the conversation regarding the probe into Flynn where Trump reportedly told Comey: "I hope you can let it go."

The meeting reportedly took place on Feb. 14, 2017, one day after Flynn resigned.

Trump said Flynn was a “good guy,” Comey said.

“I just said, ‘I agree he's a good guy’ … and so then full-stop. And there was a brief pause. And then the meeting was over,” Comey said in the interview.

Comey also said during the interview he also believes it's possible Trump is compromised by Russia.

Trump in recent days has been going on the attack against Comey. He called the former FBI director a "slimeball" and claimed he would go down as the worst FBI director in history.
