Senate Majority Leader Mitch McConnell is willing to consider a Democratic president’s Supreme Court nominee in 2021 if President Donald Trump loses reelection, calling it “politically unsustainable” to extend his blockade into the opening days of a new presidency.

McConnell on Thursday notably did not commit to confirming a nominee from Joe Biden, Bernie Sanders, Elizabeth Warren or one of the other 21 Democratic contenders. But he did acknowledge that a new president’s Supreme Court nomination would receive votes, unlike Merrick Garland’s nomination in 2016.

“Obviously, if you have a vacancy in the first year of a term of a president, you’re not going to fail to fill the vacancy for a very lengthy period of time no matter what political opposition is,” McConnell told reporters at a pre-recess news conference. “I can’t imagine any scenario under which the early part of a president’s term you would not have a vote. That doesn’t mean the person would necessarily be confirmed.”
