FAIRFAX, Va. — Joseph M. McDade, an 18-term Republican congressman from Scranton who was known for bringing federal dollars home to his district and who was acquitted in 1996 on a bribery charge, has died. He was 85. A statement from his family says he died Sunday at his home in Fairfax, Virginia. McDade was the longest-serving Republican in the House when he was indicted in 1992 on charges he accepted gifts from defense companies in exchange for helping them win lucrative contracts.
