WATCH: Lindsey Graham throws down the gauntlet, challenges Chuck Schumer in fiery interview

Democrats have already threatened to investigate — or even try to impeach — Supreme Court Justice Brett Kavanaugh should they retake control of the House after November's midterm elections.

On Sunday, South Carolina Sen. Lindsey Graham (R) responded to the news by throwing down a challenge to Senate Minority Leader Chuck Schumer (D-N.Y.).

What did Graham say?

At first, when asked about the threat, made primarily by Rep. Jerry Nadler (D-N.Y.) who is the ranking member on the House Judiciary Committee, Graham vowed to campaign against his congressional colleagues in the run up to November's elections, something he said he's never done before.

"I've never campaigned against a colleague in my life. That's about to change. I'm gonna go throughout this country and let people in these, you know, purple states, red states where Trump won know what I think about this process," Graham said on "Fox News Sunday."

Then host Chris Wallace asked Graham about a list he brought on set. Wallace was referring to the list of potential Supreme Court nominees that President Donald Trump released last year.

"What's your point?" Wallace asked.

Graham responded with force, issuing a direct challenge to Schumer.

"Here's my point. This is a list that was compiled in November, but [Trump] actually put it out during the campaign. There are 20-something people on this list. I'm asking Chuck Schumer: name five, name three, name one that would be okay with you," Graham said.

He explained:

Brett Kavanaugh was a mainstream judge. I would have chose him if I'd been president. Bush supported him. Everybody running for president on our side believed that Brett Kavanaugh and Neil Gorsuch were outstanding conservative jurists.

The other side wants to cancel the election. So Chuck, you want somebody new? Look at this list, and see if there's anybody you agree to — but what you want to do, Senator Schumer, is to overturn the election and you pick the judges. We're not gonna let you pick the judges. If you wanna pick judges, then you need to win the White House.

When Obama won, I voted for two judges that he picked. So Chuck Schumer, name one person on this list you think's acceptable.
