South Carolina Governor Mark Sanford today admitted having an affair with a woman in Argentina. He acknowledged it after returning from a secret weeklong trip there. His absence had led to a flurry of speculation about his whereabouts and activities.

GOV. MARK SANFORD (R), South Carolina: Recently, over this last year, it developed into something much more than that. And, as a consequence, I hurt her, I hurt you all, I hurt my wife, I hurt my boys, I hurt a lot of different folks. And all I can say is that I apologize.
JIM LEHRER: Sanford is barred from running again for governor, but he's been mentioned as a possible presidential candidate in 2012. He did not address his future today, but he did step down as head of the Republican Governors Association.
