Democratic Sen. Elizabeth Warren believes Attorney General Jeff Sessions should be removed from his post.
Warren made the comments to David Axelrod in an interview a day ahead of Sessions' scheduled testimony to the Senate Intelligence Committee, CNN reported.
Warren has come into conflict with Sessions before.
"I opposed Sessions for being Attorney General of the United States. And you may remember I got sent away from the Senate for that and got shut down and not allowed to speak again until after the vote," Warren told Axelrod, according to CNN.
The presenter then asked her what she thought should happen to Sessions.
"He needs to be fired. He needs to be taken out of that job," she added. "If you're not going to be honest during your confirmation hearing, then you ought to be gone."
The Justice Department issued a statement June 8 declaring that Sessions recused himself from the Russia investigation because of his involvement with the Trump campaign.
Warren believes that if Sessions had a role in the dismissal of FBI Director James Comey, that would amount to a violation of his recusal.
"Yes, yes, yes," she said when asked about it.
Sessions may decide to assert executive privilege depending on the scope of the questions the committee asks him.
Bob Graham, a former chairman of the Senate Intelligence Committee, stated that Comey's testimony last week "created a political, if not a legal situation, in which Attorney General Sessions is almost forced to answer and come forward in a public session," CBC reported.
Comey told the Senate Intelligence Committee that the FBI had become "aware of facts that I cannot discuss in an open setting" that would have made Sessions' involvement in the investigation "problematic."
Comey reportedly told the committee in closed-door testimony that Sessions met with Russian Ambassador Sergey Kislyak on three separate occasions. This is at odds with Sessions' statement during his confirmation hearing, when he said he had met with the Russian official twice.
Speaking on "Face the Nation" June 11, Senate Minority Leader Charles Schumer stated that Sessions should be placed under oath and asked about his involvement in firing Comey, his role in selecting Comey's successor, and why he failed to mention his third meeting with Kislyak during his confirmation process, the Washington Post reported.
Conservative political commentator Michael Barone is not convinced by the allegations.
"This idea there was collusion with Russia, they've been investigating for 10 months now, and nobody's found anything, far as I can tell," Barone told CBC. "Trump being thrown out of office, that's science fiction."
