Mitt Romney's videotape secretly recorded at a closed door fund-raising with wealthy donors in Florida has gone viral and sparked a severe wave of criticism, including from President Barack Obama who responded to the footage today on "The Late Show" with David Letterman.

The video, reportedly recorded in May, shows Romney telling his donors that 47 percent of the people who will vote for Obama believe they are victims and are dependent upon government.

"There are 47 percent who are with him...who believe that they are entitled to health care, to food, to housing, to you-name it," Romney says in the video.

Letterman brought up the topic on today's interview with Obama.

"Is that just -- is that what rich guys at country clubs are talking about?" Letterman asked Obama.

"One of the things I've learned as president is you represent the entire country...and my expectation is that if you want to be president, you've got to work for everybody, not just for some," Obama said.

Obama also opposed Romney's comments that his supporters see themselves as victims.

"I promise you, there are not a lot of people out there who think they're victims, there are not a lot of people who think that they're entitled to something," Obama said, "...there's nothing wrong with us giving each other a helping hand."

"If you want to be president and you want to bring people together, I think that's the attitude that you've got to have," he added.

The secret video was posted Monday on the site Mother Jones and has so far been viewed over 2 million times on YouTube. The site received almost two million page views after the story was posted, according to it's co-editor Clara Jeffery, the New York Times reported.

A second video, which is the full version of the recording, was posted on the site Tuesday.
