"And congratulations, Chuck Schumer, another you know, another term as Senate minority leader," said Biden.

The current Senate Minority Leader is Sen. Mitch McConnell, R-Ky.

"You know, I think, you know, this time you have a slightly bigger majority, Mr. Leader. You know, majority leader, but that much bigger," he clarified after.
