Mark Sanford reclaims his former seat in Congress

WASHINGTON (AP) - Republican Mark Sanford, the former South Carolina governor whose extramarital affair sank his political career in 2009, is returning to Congress to reclaim his old House seat as he forges a comeback.

A week after beating Democrat Elizabeth Colbert Busch in a special election, Sanford was sworn in Wednesday for the seat he held for three terms beginning in 1995. Sanford says he'll work with fellow Republicans even though the national party yanked its support for him just weeks before the election.

Sanford four years ago tearfully admitted an affair with a woman in Argentina, which he initially covered up by saying he was hiking the Appalachian Trail.

The seat became vacant when GOP Sen. Jim DeMint resigned last year and Republican Rep. Tim Scott was appointed to DeMint's seat.
