One of
Pennsylvania's two senators, along with
Rick Santorum. He grew up in
Kansas and first moved to
Philadelphia when he enrolled at the
University of Pennsylvania. He then took a job in the Philadelphia
district attorney's office.
However before he became a DA he was an attorney who worked on the Warren Commission, and (according to Oliver Stone's JFK) originated the single bullet theory, or if you prefer the "magic bullet theory".
Politically he is a fiscal conservative and a social libertarian.
