Marshall Clement "Mark" Sanford Jr. (born May 28, 1960) is an American politician from South Carolina, who was the 115th Governor of South Carolina from 2003 to 2011. A member of the Republican Party, he served from 1995 to 2001 as Congressman in the United States House of Representatives for South Carolina's 1st congressional district, where he held conservative positions.
In 2002, he was elected the 115th Governor of South Carolina, defeating Democratic incumbent Jim Hodges, and was reelected in 2006. As governor, he had a contentious relationship with the South Carolina legislature: notably, he made public statements that he would reject stimulus funds for his state from the American Recovery and Reinvestment Act of 2009. Following a subsequent battle in the South Carolina Supreme Court, he was forced to accept the funds.
On June 24, 2009, Sanford resigned as chairman of the Republican Governors Association, after he publicly revealed that he had an affair with María Belén Chapur, an Argentine woman. He was later censured over the affair because of misuse of state travel funds.
