On Thursday, Sanford agreed to reimburse the state for part of a more-than $8,000 tab that enabled him to see his mistress on an official economic development trip to Argentina's capital city. At a Cabinet meeting Friday, he told the head of the state Commerce Department he was sorry about the trip.
The department had initially included only Brazil on the official itinerary but added meetings in Buenos Aires at the governor's behest, said Kara Borie, a spokeswoman for the state Commerce Department.
Sanford did conduct business in Buenos Aires, although Borie said there were no specific economic development projects that have come from them.
The AP is also reporting that Republican State Senator Jake Knotts is calling for an investigation into Sanford's taxpayer-funded travel in Argentina.
