(CNN) - South Carolina's attorney general said Thursday he expects a report showing whether Gov. Mark Sanford used any public money on private travels to be released soon.
Attorney General Henry McMaster, a Republican who plans to run for governor in 2010, called for an investigation into Sanford's travel records after the governor admitted he had visited his mistress more times than he previously disclosed.
After disappearing for nearly a week, Sanford admitted last week that he'd been in Argentina with his mistress. The Republican governor later confessed that he'd seen Maria Belen Chapur several times in the past year, and that he'd also "crossed lines" with other women.
"This thing has been swirling around here for some time now, and questions have been raised all over the place. So, we thought the best thing to do, given the information that had come forward in unanswered questions, I asked the state law enforcement division to look into it," McMaster said on CNN's American Morning.
He said a report could come as early as Thursday, or as late as next week.
