House Energy and Commerce Committee Republicans asked the Environmental Protection Agency and the Departments of Commerce, Energy, and Health and Human Services October 24 to explain billions of dollars that remain unspent by the agencies each year. Committee Chairman Fred Upton (R-MI) and Oversight and Investigations Subcommittee Chairman Cliff Stearns (R-FL) have had a number of hearings as part of a planned series on cutting agency spending. The agencies have until November 7 to reply.
