Sen. David Thomas said Monday the governor's business- and first-class flights to China and London violated laws requiring the cheapest travel possible.
The Fountain Inn Republican is heading a legislative committee investigating Sanford's travel. Mr. Thomas said the tickets cost taxpayers $13,700 more than the economy-class flights available.
Sanford spokesman Benjamin Fox said Mr. Thomas is wrong and that his conclusions blatantly overreach.
Mr. Sanford meets with his Cabinet today. He has been under increased scrutiny since admitting in June to an affair with a woman in Argentina. He has vowed to stay in office.
