Not so fast Bill! US Attorney Fouratt told defense lawyers his decision not to charge Richardson “is not to be interpreted as an exoneration of any party's conduct.”

For New Mexico Gov. Bill Richardson, last Friday was long in coming — the day a federal prosecutor announced that after nearly a year investigating alleged corruption in the awarding of state contracts, he had wrapped up the case without any indictments. The investigation had cast a cloud over Richardson, scuttling a job in the Obama Cabinet and putting in doubt his political future.
But even as Richardson and his allies proclaimed his “vindication” and predicted it would catapult him back onto the national stage, the prosecutor handling the case wouldn’t let the matter fade. U.S. Attorney Greg Fouratt fired off a letter to defense lawyers asserting the inquiry "revealed that pressure from the governor's office resulted in the corruption of the procurement process,” holding out the possibility of reconvening an investigation and stressing that the decision not to charge Richardson “is not to be interpreted as an exoneration of any party's conduct.”
