When then-South Carolina Gov. Mark Sanford went MIA for nearly a week in June of 2009, his staff told the public he was out hiking the Appalachian Trail. But when the Republican was spotted at Atlanta's Hartsfield-Jackson Airport, he decided to come clean about the mysterious hiking trip and quite a bit more. Sanford admitted he was not hiking, but visiting his Argentinian mistress in Buenos Aires. Though his wife, Jenny, said she was open to reconciliation, Sanford was head-over-heels for paramour Maria Belen Chapur. The Sanfords divorced. He became engaged to Belen Chapur in August.
