Transcript for Clinton, Sanders Tangle in Democratic Debate
The democrats facing off in new Hampshire, battling one another. Hillary Clinton drawing the most fire over what she said about Donald Trump helping recruit terrorists. Tonight, trump firing back. But first, Clinton and her chief rival in the primaries settling some unfinished business over the data breach. Cecelia Vega in New Hampshire tonight. Reporter: There were three candidates on that stage, and one elephant in that room. Yes, I apologize. Reporter: Bernie sanders apologizing for his campaign's breach of Hillary Clinton's private voter database. Two more staffers suspended overnight. I very much appreciate that comment, Bernie. Reporter: But this was no love fest. Clinton and sanders tangling over everything from Wall Street -- Should corporate America love Hillary Clinton? Everybody should. Will corporate America love a president sanders? No, I think they won't. They ain't going to like me. And Wall Street is going to like me even less. Reporter: To gun control. Arming more people, I think, is not the appropriate response to terrorism. It's a country in which people choose to buy guns. That's the right of people. We have got to bring together the vast majority of the people who do in fact believe in sensible gun safety regulations. Reporter: But they were united, tag-teaming against former Maryland governor martin O'Malley, trailing in the polls. The flip-flopping political approach of Washington that both of my two colleagues on the stage have represented for the last 40 years -- Whoa, whoa, whoa. Let's calm down a little bit, martin. Yeah, let's tell the truth, martin. Reporter: And against the front-runner across the aisle, Donald Trump. Perhaps the even bigger elephant in the room. And somebody like trump comes along, and says, I know all the answers. He is becoming Isis' best recru recruiter. They are going to people showing videos of Donald Trump insulting Islam and muslims in order to recruit more radical jihadists. Reporter: Her campaign later unable to prove such video exists. Clinton delivering a few laughs too. A late arrival back to the podium during a commercial turned bathroom break. Sorry. Reporter: And perhaps the most memorable line of the night. And may the force be with you. Reporter: But the biggest disagreement of the night came well after the end of the debate. Both the Clinton and the sanders teams claiming victory. Now both sides heading to Iowa this week, Tom. Those all-important caucuses just six weeks away. The countdown on is on. Thank you.
