Salute the Marines.
A friend sent me a video clip of Obama. For some reason I can't post it. However, there is Obama talking to some late night comic and saying that if he could have a 3rd term he'd like to put one of those ear buds in the guy and speak to him and tell him what to do. It was real funny. I wish I could post it.
I would be willing bet that it was either Obama or ValJar who told him to "Salute the Marine."
They did not expect Biden to just repeat the words.
