In South Carolina, Republican Governor Mark Sanford has admitted to an extramarital affair. Sanford came under scrutiny late last week after media reports that his whereabouts were unknown. Aides said he was hiking the Appalachian trail. But on Wednesday, Sanford admitted he was in Argentina visiting a woman with whom he was romantically involved.

South Carolina Governor Mark Sanford: “The bottom line is this, I have been unfaithful to my wife. I developed a relationship with what started as a dear, dear friend from Argentina. It began very innocently, as I suspect many of these things do, in just a casual email back-and-forth in advice on one’s life there and advice here. But here, recently, over this last year, it developed into something much more than that.”

Sanford was considered among the top contenders for the Republican presidential nomination in 2012. He’s resigned as chair of the Republican Governors’ Association.
