South Carolina Gov. Mark Sanford appeared before reporters on Wednesday afternoon to admit the rumors were true; he ditched his security detail and flew to Argentina to have an extramarital affair with a "dear, dear friend."

As a result, Sanford said he let down his family and the people of South Carolina when he secretly escaped after a long legislative session had ended. After days out of contact with family and staff, rumors began to circulate as to the location of South Carolina's executive. Before he left, Sanford told staffers he was going to take a hiking trip to the Appalachian Mountains. But that story quickly unraveled after he was unreachable.

The office of South Carolina Gov. Mark Sanford late Monday cleared up a mystery, and growing concerns, about the sudden disappearance of the governor since last week. After four days of questions that even Sanford's wife could not answer, aides said the Republican had been hiking on the Appalachian Trail.

According to the State, Sanford left the governor's mansion last Thursday in a black Suburban SUV used by his bodyguards. His last known location was near Atlanta, where a cell site received a signal from one of his mobile phones. Since that time, his phones have been switched off.
