The Lion's Den: Exclusive: Warren accused Sanders in tense post-debate exchange of calling her a 'liar' on national TV

CNN)In a tense and dramatic exchange in the moments after the Democratic debate Tuesday night, Elizabeth Warren accused Bernie Sanders of calling her a liar on national television.

Sanders responded that it was Warren who called him a liar and said they should not talk about it right then.

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.

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."
