WASHINGTON — Oklahoma Attorney General Scott Pruitt blasted the Obama administration's plan to reduce greenhouse gas emissions on Thursday, saying at a House hearing that it was an unconstitutional power grab by “politically unaccountable bureaucrats.”

The Clean Power Plan, as written, would make the EPA “a central planner for every single industry that emits carbon dioxide,” Pruitt told the House subcommittee on the

environment.

A Democratic congressman on the panel questioned Pruitt's relationship with oil and gas companies in Oklahoma, citing a New York Times story about letters drafted by Devon Energy, of Oklahoma City, and sent with few changes by Pruitt's office to the EPA, the White House and the Interior Department regarding methane gas emissions.

“The ethical issues this presents are disturbing,'' said Rep. Mark Takano, of California.
