Trent Lott was quick, in his two appearances yesterday, to rule out health and scandal as reasons for his sudden and very surprising resignation from the Senate. But Washingtonians know that whenever a politician leaves to "spend more time with his family," there are likely to be other reasons. Sources in Mississippi law enforcement inform No Comment that FBI agents are now raiding the law office of Richard "Dickie" Scruggs in Oxford. Scruggs is the brother-in-law of Trent Lott, and, as we reported earlier, several Mississippi newspapers openly questioned whether Lott had intervened to protect Scruggs in a recent criminal probe that produced the prosecution of a number of other Mississippi lawyers and judges with whom he was closely connected. Could there be a connection between the FBI raid and the Lott resignation? Just asking.
