From an excerpt provided by the White House: "I am seriously glad to be here tonight at the annual Alfalfa dinner. I know that many of you are aware that this dinner began almost one hundred years ago as a way to celebrate the birthday of General Robert E. Lee. If he were here with us tonight, the General would be 202 years old. And very confused."
