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.
"I will tell you that visits of this nature are not that uncommon," she said, noting the results aren't always immediately evident.
But the furor over Sanford's trip is mushrooming. Critics called on the State Law Enforcement Division to investigate state spending on the trip and whether Sanford broke laws by leaving on his latest visit to Argentina last Thursday without turning control over to the lieutenant governor. His staff told people who asked that he was hiking on the Appalachian Trail.
"We also have to worry about whether this is the tip of the iceberg. We don't know what else is out there. We don't know what's going to come out tomorrow. We don't know what's going to come out next," said state Sen. Jake Knotts R-West Columbia.
The law enforcement agency said it was reviewing Knotts' request, but hadn't opened a criminal investigation involving Sanford as of Friday.
"To date, given the information we know, we do not believe that there will be a criminal investigation launched," agency spokeswoman Jennifer Timmons said.
Also calling for inquiries were the state chapter of government watchdog Common Cause and the Washington-based nonprofit Citizens for Responsibility and Ethics, which directed its request to the state ethics commission.
Sanford got back to work Friday, meeting with his Cabinet in front of about two dozen reporters and cameramen. Routine business included a discussion of tax revenues and a drunken driving campaign, but Sanford's first public meeting since returning from Argentina Wednesday was hardly ordinary.
