Recent Senate debates in the 112th Congress over judicial nominations have focused on issues such as the relative degree of success of President Barack Obama's nominees in gaining Senate confirmation (compared with other recent Presidents) as well as the effect of delayed judicial appointments on judicial vacancy levels. The following report addresses these issues, and others, by providing a statistical overview of President Obama's nominees to U.S. circuit court of appeals and U.S. district court judgeships, current through May 31, 2012.

The use of biomass as an energy feedstock is emerging as a potentially viable alternative to address U.S. energy security concerns, foreign oil dependence, rural economic development, and diminishing sources of conventional energy. Biomass (organic matter that can be converted into energy) may include food crops, crops for energy, crop residues, wood waste and byproducts, and animal manure. Most legislation involving biomass has focused on encouraging the production of liquid fuels from corn. For over 30 years, the term biomass has been a part of legislation enacted by Congress for various programs, indicating some interest by the general public and policymakers in expanding its use. To aid understanding of why U.S. consumers, utility groups, refinery managers, and others have not fully adopted biomass as an energy resource, this report investigates the characterization of biomass in legislation.
