"In the year after the invasion of Iraq in 2003 nearly 281 million notes, weighing 363 tonnes, were sent from New York to Baghdad for disbursement to Iraqi ministries and US contractors. Using C-130 planes, the deliveries took place once or twice a month with the biggest of $2,401,600,000 on June 22 2004, six days before the handover.Details of the shipments have emerged in a memorandum prepared for the meeting of the House committee on oversight and government reform which is examining Iraqi reconstruction. Its chairman, Henry Waxman, a fierce critic of the war, said the way the cash had been handled was mind-boggling. "The numbers are so large that it doesn't seem possible that they're true. Who in their right mind would send 363 tonnes of cash into a war zone?"
