House Ways and Means Subcommittee on Oversight Chairman Charles Boustany (R-LA) requested documents and information May 3 to investigate whether departments require contractors to pay back percentages of an energy efficiency tax deduction. The request comes in the wake of the committee receiving documentation that suggests that the General Services Administration may be using the Energy Efficient Commercial Buildings Deduction to get additional money from contractors. The congressman requested that the information be sent by May 18.
