Samuel James Ervin Jr. (September 27, 1896 – April 23, 1985) was an American politician who served as a U.S. Senator from North Carolina from 1954 to 1974. A Southern Democrat, he liked to call himself a "country lawyer", and often told humorous stories in his Southern drawl. During his Senate career, Ervin was at first a staunch defender of Jim Crow laws and racial segregation, as the South's constitutional expert during the congressional debates on civil rights. However, unexpectedly, he became a liberal hero for his support of civil liberties. He is remembered for his work in the investigation committees that brought down Senator Joseph McCarthy in 1954 and especially for his leadership of the Senate committee's investigation of the Watergate scandal that led to the resignation of President Richard Nixon in 1974.
