House moves to rein in EPA

A U.S. House committee approved a bill Tuesday to block a federal agency from regulating greenhouse gases, but the real drama broke out in the Senate, where Oklahoma Republican Jim Inhofe is pushing the measure. Senate Minority Leader Mitch McConnell, R-Ky., introduced Inhofe's bill as an amendment to a small-business measure. McConnell said the time had come for the Senate to take a stand on the legislation, which is designed to strip the U.S. Environmental Protection Agency of its authority to regulate greenhouse gases in response to climate change. But following hours of strongly worded debate, an attempt to reach an agreement on holding floor votes Tuesday evening apparently failed.
