"Go watch tapes from the Democratic convention," Gingrich said. "You have people who had extraordinary opportunities in the most open society in the world who explain how they're victimized and government should take care of them. It's the heart of the Obama majority, people who would like someone to take care of them."

The Obama campaign released its first ad pouncing on the "47 percent" comment Monday.

"Mitt Romney attacked 47 percent of Americans who pay no income tax — including veterans, elderly, the disabled," the ad's narrator says, before a clip of Romney saying his "job is not to worry about those people" plays.

"Doesn't the president have to worry about everyone?" the narrator asks.

During an interview with "60 Minutes" on Monday, Romney admitted, in reference to the remarks, that "not everything I say is elegant," but said his words were being misinterpreted.

"I want to make it very clear, I want to help a hundred percent of the American people," Romney said.
