William Jefferson Clinton (born William Jefferson Blythe III; August 19, 1946) is an American politician who served as the 42nd president of the United States from 1993 to 2001. Prior to his presidency, he served as governor of Arkansas (1979–1981 and 1983–1992) and as attorney general of Arkansas (1977–1979). A member of the Democratic Party, Clinton was known as a New Democrat, and many of his policies reflected a centrist "Third Way" political philosophy. He is the husband of former Secretary of State and former U.S. Senator Hillary Clinton. In 1998, Clinton was impeached by the House of Representatives and is one of only three U.S. presidents to have been impeached. The impeachment was based on accusations that Clinton committed perjury and obstruction of justice for the purpose of concealing his affair with Monica Lewinsky, a 22-year-old White House intern. He was acquitted by the Senate and completed his term in office.
