Rockefeller, Byrd Target Obama EPA over Climate Change

U.S. Sens. Robert C. Byrd and Jay Rockefeller, both D-W.Va., have joined six caucus colleagues from natural resource-rich states in "challenging the Environmental Protection Agency's authority to regulate pollution blamed for global warming," The Associated Press reports.

Rockefeller wrote the letter signed by all eight that argues "the agency lacks the power to restrict greenhouse gases," the article said, adding that "Their opposition could pose a blow to the Obama administration's anti-pollution efforts."

Rockefeller's office has posted the letter online, along with a press release.
