 His political background is a little unclear. He was a registered Republican, but also had donated a couple years ago a small amount of money, $15 or so, to a Democratic organization. He was a member of a gun club near his home, the Clareton Sportsman's Club. They confirmed as much to me, but they wouldn't say anything more about what he did there. The FBI, for its part, is talking to his family, and officials say that the family is cooperating with the investigation.
