Fan Casting Senator Robert Emmett "Bob" Haynes in Of Angels and Demons

Everybody knows him as a proud Republican senator: Christian, moralistic, anti-gay, anti-cannabis, anti-Islam... But he's actually, a closeted gay man with a preference for Asian males. At the beginning of the story he's arrested for public indecency at the Detroit Airport restroom for having sex with two male prostitutes, losing his airplane for Denver, where he had to make a speech against cannabis. At the police station, he meets Satan, who recruits him.
