"I think you called me a liar on national TV," Warren told Sanders according to a recording released by CNN.

"What?" The Vermont Senator responded.

"I think you called me a liar on national TV," she repeated.

"You know, let's not do it right now. If you want to have that discussion, we'll have that discussion," Sanders said.

"Anytime." Warren shot back.

"You called me a liar,” Sanders then countered. “You told me — all right, let's not do it now.
Sanders is right, that wasn't the place to have that conversation but if Warren is bold enough to confront him over it, it makes her look like she's telling the truth.
