Good onning. I'M cynthia McFadden. We begin with breaking news a secretly recorded tape at a mitt romney fund-raiser with content so controversial that it led the controversial nominee to speak out tonight. The tape earlier this year captures the presidential hopeful, saying that nearly half of the american voters are living off the government and believe they are victims. David muir has the latest on the developing story. Tonight mitt romney walking up with a smile but his campaign is in mode this evening. I understand there's a video on the internet for a few weeks that's attract the some attention. Reporter: That video posted in snippets shows mitt romney in a partially blurred out video speaking to wealthy fund raisers. Romney said nearly half of the americans believe they're victims, and goes on to say his job is not to worry about those people. There's 47% who vote with him no matter what. 47% who are with him, who are dependent on government. Who believe the government has the responsibility to care for them. Who believe they're entitled to health care, food, housing, you name it. That's entitlement. They will vote for this president no matter what. Reporter: He said those people pay no income tax. My job is never worry about those people. They should take personal responsibility and care fof their lives. What I have to do is convince the 5% to 10%. Reporter: Romney goes on to say how he plans to reach those voters some who voted for barack obama. You say do you think barack obama is a failure? They say no. They like him. Reporter: On the political website, audio from what is believed to be the same fund-raiser. Talking about his father born in mexico to american parents. Romney said had he been born to mexican parents, he would have a better chance of winning. My dad, as you probably know was the governor of michigan and was head of a car company but he was born in mexico. Had he been born of mexican parents I would have a better shot of winning. Reporter: About the perceptions he was born to a privileged home. There's the perception that i was born with a silver spoon. Reporter: He says 95% is set up for you if you're born in this country and shares the strategy of using ann on the trail. Use ann sparingly so people don't get tired of her. Reporter: Romney said whoever released the snippets should release them in their entirety. Whatever released them, release the whole tape so we can see all of it. Reporter: Romney saying he never could convince americans to take personality responsibility for their lives? Of course individuals are going to take responsibility for their life. My campaign is about helping people take more responsibility and becoming employed again. Particularly those that don't have work. My campaign is focused on getting people jobs again. It's shocking that a candidate that the president of the united states would go behind closed doors and declare to wealthy donors that half of the american voters view themselves as victims. President obama had his own moment caught on tape in a private fund racer, whzor, where he said some cling to their guns in religion. Four years later romney explains his own words after the campaign gave them no bounds and the president leading many in the key battleground states. As for the person who took that video. He does not work for the obama campaign or democratic party. Tonight governor romney stood by the 47% argument. Saying people that get help from the government might not like his plan for less government, when he talked about sliver of independent voter, he talked about the ones who voted for president obama before. He actually said many of them love the phrase that he's over his head in talking about president obama. The question is, will they love hearing that phrase said behind closed doors now?
