A senior U.S. officer close to top Iraq commander General David Petraeus is among dozens of people under investigation for illicit activity in the sale and delivery of billions of dollars in weapons in Iraq. The New York Times reports the widening probe has already led to several indictments. The multi-agency investigation includes the Army Criminal Investigation Command, the Department of Justice, the FBI and others. The senior officer, Lt. Col. Levonda Joey Selph, worked closely with General Petraeus to set up logistics services for Iraqi forces.
