President Obama reacted to the Mitt Romney video on the 'Late Show.' The president told David Letterman, “One of the things I’ve learned is you represent the entire country, and when I meet Republicans as I’m traveling around the country, they are hard working family people who care deeply about this country. And my expectation is that if you want to be president you got to work for everybody, not just for some.”
