Oh crap. Governor Mark Sanford has announced that he’s been carrying on an affair with a woman in Argentina, and he will resign his post at the Republican Governor’s Association immediately.

“I’ve been unfaithful to be my wife,” Sanford said at a state capitol news conference.

It began very innocently,” he explained, saying that developed into an adulterous relationship in the past year.

He said he seen his unidentified mistress three times since they began the affair or, as he put it, “since the whole sparking thing.”

A tearful Sanford said that his wife knew about the affair prior to his recent trip, and that they’ve been attempting to work through the difficult time for a period of five months.

He shed tears as he explained how helpful one friend had been.

Sanford’s admission caps an extraordinary week in which he was revealed to having been in Argentina and not, as his staff said, hiking on the Appalachian trail.

Before disclosing his relationship, Sanford apologized profusely to a number of family and friends.

“I’ve let down a lot of people — that’s the bottom line,” Sanford said.

The press conference was a bit rambling, starting off with how he used to love hiking the Appalachian Trail.
