Contrary to his assertion that he would "not accept a supplemental over $108 billion," President Bush signed a $257 billion war supplemental spending package on June 30. The bill will fund the wars in Iraq and Afghanistan for the remainder of the fiscal year (ending Sept. 30) and through the first several months of the next president's term.

In a recently released report, the Government Accountability Office (GAO) examined ten years of supplemental spending (FY 1997-FY 2006) and found not only a five-fold increase in the amount of expenditures funded through the supplemental process, but also that procedures that enable legislative deliberation are bypassed when Congress funds government operations through supplemental spending. Supplemental spending has become an alternative funding process, parallel to the normal annual appropriations process. This allows certain expenditures to elide close congressional and public scrutiny and allows Congress to escape debate over federal funding priorities.

The Bush administration's emergency supplemental spending requests for the wars in Afghanistan and Iraq have lacked the transparency that normally accompanies the appropriations process, according to a new report from the Congressional Budget Office (CBO). In addition, the CBO war spending report, however constrained by available data, revealed the composition of the war funding requests has been evolving into broader Defense Department spending initiatives, such as acquiring next-generation aircraft and replacing aging aircraft.

Congress will soon begin work on the largest supplemental funding bill ever requested — $99.6 billion — to continue to fund the wars in Iraq and Afghanistan, along with other items. The request was submitted to Congress by the president in early February, when the FY 2008 budget was released. If approved, this request would add $93.4 billion to the $70 billion Congress already appropriated for the "war on terror" in FY 2007 and bring the total cost of the wars to over $500 billion.
