Congress has received President Obama's budget request for FY2014, which includes $142.773 billion for research and development (R&D), a $1.861 billion (1.3%) increase from the FY2012 actual funding level of $140.912 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.
