Mark Sanford has supposedly agreed to repay his travel expenses from the trade mission trip to Brazil that was extended to Argentina at his request so he could meet up with his lover.  He certainly wasn't traveling alone.  He should have to pony up for the expenses for ALL members of his trade committee traveling party that incurred additional travel costs by going from Brazil to Argentina.  The Argentina trade meetings apparently were quickly put together at Sanford's request and nothing in terms of business has resulted from the additional costs that South Carolinians incurred from Sanford's illicit liason.
