Congressional Research Service. June 14, 2012.

Congress has received President Obama’s budget request for FY2013 which includes $140.820 billion for research and development (R&D), a $1.951 billion (1.4%) increase from the FY2012 estimated funding level of $138.869 billion. The request represents the President’s R&D priorities; Congress may opt to agree with part or all of the request, or may express different priorities through the appropriations process. In particular, Congress will play a central role in determining the extent to which the federal R&D investment can grow in the context of increased pressure on discretionary spending and how available funding will be prioritized and allocated. Low or negative growth in the overall R&D investment may require movement of resources across disciplines, programs, or agencies to address priorities.
