Barack Obama Defends Criticism of McCain's "100 years" comment

Barack Obama recently criticized John McCain for allegedly saying he'd be willing to send American troops into another 100 years of war in Iraq. Meredith Vieira, co-anchor of the "Today Show" interviewed Barack Obama and asked him the following: "Senator McCain never said he wanted a 100 more years of war. He just felt American troops should be a long term presence the way they are in Japan and South Korea. So are you willing to admit that you have distorted his statements?"
