COLUMBIA, S.C. — Gov. Mark Sanford on Wednesday repaid the South Carolina general fund an additional $334 after The State newspaper questioned how much he had reimbursed taxpayers for a June 2008 trip to see his Argentine lover.

Spokesman Joel Sawyer said the governor's office miscalculated meals and miscellaneous travel expenses after The State asked how the $3,000 he repaid Tuesday evening was calculated.

"It was a clerical mistake, period," Sawyer said. "We made the governor aware of it immediately."

A Sanford staffer hand-delivered the check to state treasurer Converse Chellis' office about 10 minutes after a call from the newspaper, the treasurer's spokesman Scott Malyerck said.

Sanford, under pressure to resign after admitting to a love affair with Maria Belen Chapur, volunteered to reimburse taxpayers for his and a Commerce department staffer's expenses for the Argentine leg of a 2008 trade mission to that country and neighboring Brazil.

Records show Sanford met with Argentine business and government officials during the June 24-27, 2008, Argentine portion of that trip. But he's also acknowledged that was when his relationship with Chapur became physical.
