Famous Quote: "The fundraisers I go to are all open bar. I don't think I'd go to one that wasn't."

Famous Quote: "But at the end of the day, it's better if the world can see who I am and [that] the choices that I've made are reflected. Because ultimately the choices that I've made in life, on balance, represent ME. And for most of us, that's a good thing."
