"On February 15, 2007 President Bush signed into law P.L. 110-5 (H.J.Res 20), which provides funding for the nine outstanding regular appropriations bills through September 30, 2007.The 109th Congress passed two appropriations bills, the Department of Defense (P.L. 109-289, H.Rept. 109-676) and the Department of Homeland Security (P.L. 109- 295, H.Rept. 109-699). P.L. 110-5 will fund most agencies at FY2006 levels through September 30, 2007. However, P.L. 110-5 contains some exceptions to those guidelines, including the centerpiece of the President's proposed FY2007 R&D budget, the American Competitiveness Initiative (ACI). Agencies are required to report their estimated FY2007 R&D funding levels to Congress by March 15, 2007. The Bush Administration had requested $137.7 billion in federal research and development (R&D) funding for FY2007. That sum represented a 2.4% increase over the estimated $134.5 billion that was approved in FY2006. As in the recent past, the FY2007 increase over the FY2006 estimated funding levels was due to significant funding increases for the Department of Defense (DOD) and the National Aeronautics and Space Administration's (NASA's) space vehicles development program."
