WASHINGTON (AP) - The Justice Department today closed its investigation into whether the FBI's former deputy director tried to obstruct an inquiry into the deadly 1992 seige at Ruby Ridge, Idaho, saying it lacked evidence to bring criminal charges, governent officials said. The Justice Department decided not to bring charges against former FBI Deputy Director Larry Potts or Danny Coulson, Potts' deputy during the 1992 seige at the remote cabin of white supremacist Randy Weaver, said government officials who spoke on condition of anonymity. The Justice Department informed lawmakers and lawyers for the FBI agents that its review did not warrant any further criminal charges, but it left open the possibility of disciplinary action. The department said in a statement obtained by The Associated Press, "The available evidence does not support further criminal prosecution of FBI officials ... from the August 1992 incident at Ruby Ridge."
