Scandal-hit US Governor Mark Sanford today told his state agency chiefs that he is sorry for keeping them in the dark when he went to Argentina to see his mistress. The Republican held his usual public meeting with the agency chiefs, but started with apologies and likening his confession and future to the biblical plight of King David. South Carolina governor Mr Sanford said King David fell mightily but picked up the pieces and built from there. He made specific apologises to the head of agencies that handle his security and economic development trips, saying he put those leaders in awkward positions.
