Forty-seven House republicans, led by Energy and Commerce Subcommittee on Energy and Power Chairman Ed Whitfield (R-KY) and Representatives Mike Pompeo (R-KS) and Joe Barton (R-TX), sent a letter September 21 to Speaker of the House John Boehner (R-OH) urging him to let the wind energy production tax credit expire at the end of the year. House Majority Whip Kevin McCarthy (R-CA) has expressed support for extending the credit for at least one year.
