‘I’m a citizen with no country:’ Mark Sanford on turning against Trump and his party

Former South Carolina governor talks about his memoir that links his decision to lessons learned from an extramarital affair in 2009 and his attempt to cover it up

Mark Sanford is not the first Republican to turn against former US president Donald Trump and pay a political price. But he is unique in publishing a memoir that links his decision to lessons learned from an extramarital affair and his attempt to cover it up.

Sanford was the governor of South Carolina when, in 2009, he flew to Argentina to be with a woman who was not his wife but told his staff he was hiking the Appalachian Trail. The falsehood was rapidly exposed, made lurid headlines and ended his 20-year marriage.
