You can find NBC Nightly News anchor Brian Williams on television, the Web, and even in the back seat of a New York City taxi -- so why does he refuse to tweet?
Arianna set out to find the answer at the third annual Game Changers event, hosted by The Huffington Post. She caught up with Brian backstage after he presented to Food Game Changer, Kelly Meyer, for her work to bring healthy food to schools. Arianna took questions from Huff Post users and she and Brian touched on his love of slow-jamming the news, his day job, and...fuzzy microphones. Check out the video above to hear what Williams had to say.
