In 2003, caravans of trucks began to arrive at Andrews Air Force Base outside Washington on a regular basis, unloading an unusual cargo - pallets of shrink-wrapped $100 bills. The cash, withdrawn from Iraqi government accounts held in the United States, was loaded onto Air Force C-17 transport planes bound for Baghdad. Exactly what happened to that money after it arrived? Finding the answer became first the job and then the obsession of Stuart W Bowen Jr. His investigators finally had a breakthrough, discovering that $1.2 billion to $1.6 billion had been stolen and moved to a bunker in rural Lebanon. Bowen kept the discovery and his investigation of the cash-filled bunker ... secret. He has never publicly discussed it until now. Billions of dollars have been taken out of Iraq over the last ten years illegally," he said. The money ... came from the Development Fund of Iraq, which was created by a United Nations resolution in May 2003 to hold Iraqi oil revenue. An advantage of using the cash from the Development Fund instead of money appropriated by Congress for Iraq was that there were not a lot of rules governing its use, and no federal regulations or congressional oversight of what happened to it. The CIA expressed little interest in pursuing the matter, and the FBI said it lacked jurisdiction, Bowen recalled. An informant told [Bowen] about the bunker, which in addition to the cash, was believed to also have held approximately $200 million in gold belonging to the Iraqi government.
