Jimmy Fallon addressed Mitch McConnell's refusal to speak to Elizabeth Warren during an interview with the senator on Tuesday night.

"Mitch..Mitch McConnell you have to say hi to Elizabeth Warren," Fallon said while looking at the camera. "I mean how are are we now? This is silly. We have to be civil."

The remarks came after Fallon asked Warren what Senate Majority Leader McConnell says to her after she says hello to him.

"Nothing," Warren responded.

McConell's avoidance of Warren first became known when the senator spoke about her experience with the majority leader in an interview with the Boston Globe earlier this month while promoting her book.

"I've spoken to him, but he has not spoken to me," Warren said. "I say hello to Mitch every chance I get, and he turns his head."
