When the CNN/Des Moines Register debate concluded, the studio audience and viewers saw Warren walk over to Sanders and not shake his outstretched hand. The two senators seemed to have a heated and brief exchange before Sanders appeared to throw his hands up, turn and walk away. The video of the exchange aired live with no audio.

But sound of the moment was caught by CNN’s microphones and found Wednesday.

“I think you called me a liar on national TV,” Warren can be heard saying.

“What?” Sanders 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, to which Warren replied, “Anytime.”

“You called me a liar,” Sanders continued. “You told me — all right, let’s not do it now.”

After their exchange, fellow Democratic candidate Tom Steyer, who had been standing behind the two senators, can be heard saying, “I don’t want to get in the middle. I just want to say hi Bernie.”

I find this whole thing to be fairly uncomfortable but I do have to say that the person who walks across the stage to confront somebody for calling them a liar is very likely sincerely convinced that they are in the right. 

I know a lot of people don’t want to talk about this kerfuffle but this is a real news story now and I think we deserve to learn the truth. 

At this point I am leaning toward Warren’s side on this.
