Republican state Sen. David Thomas has accused Sanford of abusing his position of authority during two trips taken to London and China, charging $13,700 to the state could have been avoided if he had sought the most economical airfares as required by state law, CNN reported Tuesday.
Sanford, 49, is already under fire for disappearing for nearly a week in June. The married governor eventually admitted he was visiting a mistress in Argentina.
"The two flights by Gov. Sanford were in violation of the South Carolina Code of Regulations," Thomas said in a letter to members of a legislative oversight committee. "The difference in price between the most economical and the more expensive price of the seats the governor chose is approximately $13,700."
Thomas told CNN he thought the violations were enough to trigger impeachment proceedings.
