I have no independent information on this, but the Trent Lott story may have a new twist. Click on the link at your own discretion. It would seem completely impossible, if it weren't for the recent past. (Some possibly relevant context here.) A reader posits an alternative theory:

Through my journalism work, I hear Lott is actually resigning in order to try and head off a really bad scandal. Somebody was threatening to air photos of him being polite to a black person.
