For Brian, this opportunity is a dream come true. "In a couple of days I'm going to be standing in a room with two living presidents and a former first lady," he says. "I don't care who they are, what your politics are—that's a pretty incredible experience."
Jenna says she's nervous. "I'm the one sitting down to ask the questions," she says. "Usually on something like this, I'm with Oprah and she's the best interviewer in the world."
