HARRISBURG, Pa. (AP) — Former Congressman Bud Shuster, an influential Republican who strongly backed transportation projects but once ran afoul of ethics guidelines, has died at 91. A close family friend, Rebekah Sungala, said Shuster died peacefully at his farm Wednesday in Everett, Pennsylvania, surrounded by his family. His son, Bill Shuster, succeeded his father in the southern Pennsylvania seat. Sungala said Shuster died of old age. Congressman John Joyce, who now represents the area, called Shuster a “true legend in the halls of Congress.” Shuster resigned in 2001, right after he was sworn in for his 15th term, because he was losing his committee chairmanship.
