John P. Murtha has dedicated his life to serving his country both in the military and in the halls of Congress. He had a long and distinguished 37-year career in the U.S. Marine Corps, retiring from the Marine Corps Reserve as a colonel in 1990. The first Vietnam War combat Veteran elected to Congress, he has been serving the people of the 12th Congressional District since 1974.

Rep. John Murtha, the tall, gruff-mannered former Marine who became the de facto voice of veterans on Capitol Hill and later an outspoken and influential critic of the Iraq War, died Monday. He was 77. The Pennsylvania Democrat had been suffering from complications from gallbladder surgery. He died at Virginia Hospital Center in Arlington, Va., with his family at his bedside, the hospital said.

In 1974 Murtha, then an officer in the Marine Reserves, became the first Vietnam War combat veteran elected to Congress. Ethical questions often shadowed his congressional service, but he was best known for being among Congress’ most hawkish Democrats. He wielded considerable clout for two decades as the ranking Democrat on the House subcommittee that oversees Pentagon spending.

Murtha was born June 17, 1932. The former newspaper delivery boy left college in 1952 to join the Marines, where he rose through the ranks to become a drill instructor at Parris Island, S.C., and later served in the 2nd Marine Division. He settled in Johnstown, then volunteered for Vietnam, where he served as an intelligence officer and earned a Bronze Star and two Purple Hearts.

Murtha’s opposition to the Iraq war rattled Washington, where he enjoyed bipartisan respect for his work on military issues. On Capitol Hill, Murtha was seen as speaking for those in uniform when it came to military matters.
