Marshall Clement "Mark" Sanford Jr. (born May 28, 1960) is an American politician and author who served as the U.S. representative for South Carolina's 1st congressional district from 1995 to 2001 and again from 2013 to 2019, and also as the 115th governor of South Carolina from 2003 to 2011. He is a member of the Republican Party.
Sanford was first elected to Congress in 1994. He represented South Carolina's 1st congressional district in the United States House of Representatives from 1995 to 2001. He decided against running for a fourth term in the house and instead focused on running in the 2002 gubernatorial election. In the election, he defeated Democratic incumbent Jim Hodges with 52% of the vote. Sanford ran for reelection in 2006, defeating businessman Tommy Moore with 55% of the vote. As governor, Sanford attempted to reject $700 million in stimulus funds for South Carolina from the federal Recovery Act passed in 2009, but the South Carolina Supreme Court ruled that only the state legislature—not the governor—had the authority to accept or decline the funds.
In June 2009, after having disappeared from the state for nearly a week, Sanford publicly revealed that he had engaged in an extramarital affair. He had led his staff to believe that he was going hiking on the Appalachian Trail, but actually went to visit his mistress, Maria Belén Chapur, in Argentina. Although the scandal made national headlines, leading to his censure by the South Carolina General Assembly and his resignation as chair of the Republican Governors Association, Sanford did complete his second term as governor.
Sanford ran for Congress again in a 2013 special election for his old seat. He won the election and served in Congress from 2013 to 2019. He lost his 2018 reelection bid in a Republican primary. In September 2019, Sanford announced his candidacy for the Republican nomination in the 2020 United States presidential election. He dropped out of the race on November 12, 2019.
