Republican John Peterson, of Pleasantville, in Venango County, was elected to Congress representing Pennsylvania's 5th District in 1996. He was re-elected to a sixth term last year, but unexpectedly announced in January that he would retire at the end of the current term. Last week, WPSU/Capitol Hill Correspondent Sara Sciammacco sat down with John Peterson to take a look back over his time in Congress, and to get his thoughts on what lies ahead.
