Rep.-elect Mark Sanford (R-S.C.) will be sworn in Wednesday as the new representative of South Carolina's 1st district, his spokesman announced Tuesday.

In the House chamber, Sanford will be sworn in approximately 5:15 p.m. Wednesday, spokesman Joel Sawyer said. The Republican will rejoin Congress a week after he defeated Democratic nominee Elizabeth Colbert Busch by nine points, even as he was barraged by Democratic outside spending.

Sanford, the former governor who fell from grace in 2009 when he disappeared from the state and then admitted to an extramarital affair, represented the 1st district from 1995-2001.

"Fox News Sunday" host Chris Wallace asked Sanford over the weekend whether he intends to be a team player or an independent voice in the House.

"I'm a Republican who has always had an independent streak. I guess that would be the best way to define it," Sanford responded.
