Now, Kathy Griffin's telling a few different versions of this story, so we don't know if it's literal. But I think we can assume that something close to this did actually happen, and if it did, good for her!
Kathy Griffin had the extreme pleasure of bumping into Michele Bachmann at a political event; the two ladies recognized one another and when they started to speak an assistant filmed the exchange, supposedly for Bachmann's website. Kathy, always on top of her game, decided to ask the tea party princess if she'd attend a rally to repeal DADT — and when Bachmann said no, Griffin followed up with, "Were you born a bigot or did you grow into one?" Boom.
