Mark Sanford, Republican Senator, Faces 37 Ethics Viloations

Eighteen of the counts allege that he authorized first or business class flights for himself to or from Tokyo, Beijing, London, Sao Paulo and other cities when he should have flown coach.

Nine counts allege that he used state planes for personal trips, including one from North Myrtle Beach to the state capital of Columbia about 140 miles away to get a haircut and another to attend a son's sporting event.

He also made trips to attend a book signing and a birthday party for a campaign contributor, the ethics commission said.

Sanford admitted to his affair a week after a mysterious disappearance, when his staff said he was hiking the Appalachian Trail. He later said he had flown to Argentina to visit his lover.
