If I were a reporter in South Carolina, I would be tracking down Sen. Tom Davis and some of the other Sanford friends that the governor got particularly emotional about during his news conference. I'd ask the old Watergate question -- what did you know, and when did you know it?
It sounded like some of these friends knew about the affair. What did the staff know? And if the friends knew, why didn't they try to put a stop to the "missing governor" line or the Appalachian Trail story?
Presumably they didn't feel they could act without Sanford's okay, which apparently they couldn't get while he was in Argentina.
