Ending Don't Ask, Don't Tell (December 2010)

I got the opportunity to be on stage with him when he signed the bill, and my favorite moment of that day was when he was in the middle of signing his name. I just couldn't believe that it was actually happening. I was so excited, and so I somewhat spontaneously blurted out, 'Please make sure you spell it right,' to the president. He laughed. It was a great moment. It was a historic moment I think for America.
