Glenn Morshower (on his 24 character, Agent Aaron Pierce): Aaron Pierce is who I am on a good day. Aaron has a respect for the office of the president, period. He has so much respect for the office that he refuses to allow his own personal opinion to creep in and blur things. I don't think he taps into that. He just taps into, 'What I see in front of me is a U.S. president.'
