The U.S. military has already spent most of the $65 billion approved by Congress to pay for wars in Iraq and Afghanistan. Now they are struggling to find 12.3 billion more within the Defense Department budget to finance military action through the end of the fiscal year. This according to a report out from the U.S. Government Accountability Office, the most in-depth study of the military’s funding problems. The report contradicts White House assurances that the services have enough money to get through the calendar year. The Army, which is overspending its budget by $10.2 billion for operations and maintenance, is asking the Marines and the Air Force to help cover the escalating costs of its logistics contract with Halliburton Co.
