In President Obama's first response to the Mitt Romney 47 percent video, he told David Letterman: "If you want to be president, you have to work for everyone, not just for some."
Obama's remarks came after a secretly taped and newly released video showed the Republican presidential nominee describing "47 percent of the people" as Obama supporters who depend on government and believe they are victims.
"My expectation is that if you want to be president, you have to work for everyone, not just for some," Obama said in a taping of the "Late Show" with David Letterman.
It was Obama's first response to the Romney video, which roiled Romney's campaign and put him on the defensive about his views about nearly half the nation. The president appeared on the TV show before a night of fundraising in New York City.
In the video, taken during a May fundraiser and posted online Monday, Romney said it is not his job "to worry about those people." He was referring to what he called Obama's locked-in supporters who believe they are "entitled to health care, to food, to housing, to you name it."
