"I asked Attorney General [Jeff] Sessions what I thought would be the ultimate softball when he testified. I said — I may not have said it this way — at least you got to tell us that there has been no discussion of pardons at this point. And he did not answer," Warner told Vox in an interview.

"The possibility of presidential pardons in this process concerns me and also would be, I think, a really, really bad move," he added.

The Senate Intelligence Committee has an ongoing investigation into alleged collusion between the Trump campaign and Moscow during the presidential campaign.

Warner's interview comes after Donald Trump Jr. released a stunning chain of emails this week detailing his conversations about setting up a campaign meeting with a Russian lawyer.

The information “would incriminate Hillary and her dealings with Russia and would be very useful to your father,” reads one of the emails from Rob Goldstone, who acted as an intermediary to set up the meeting.

The New York Times first reported the meeting on Saturday.

Warner said earlier this week that emails published by Trump Jr. showed "black and white" that the Trump campaign was involved in Russian efforts to influence the presidential election.
