WASHINGTON (AP) — When President-elect Donald Trump's choice to head the U.S. Environmental Protection Agency first took office as Oklahoma's attorney general, he disbanded the unit responsible for protecting the state's natural resources. Records also show that Pruitt, a Republican who faces a Senate confirmation hearing Wednesday, failed to push a legal challenge initiated by his predecessor to protect Oklahoma's rivers from pollution caused by animal waste, after receiving tens of thousands of dollars in campaign contributions from individuals connected to the poultry industry. In Oklahoma, he joined with other Republican attorneys general in opposing the Obama administration's Clean Power Plan, which seeks to limit planet-warming carbon emissions from coal-fired power plants. Like Trump, Pruitt has also publicly cast doubt on the extensive body of scientific evidence showing that the planet is warming and that man-made carbon emissions are to blame. Of 14 lawsuits in which Pruitt challenged federal environmental regulations, in all but one of those cases his co-litigants included companies whose executives had made campaign donations supporting him, according to an analysis by EDF Action, the political advocacy arm of the Environmental Defense Fund. Pruitt let expire a 2003 agreement between Arkansas and Oklahoma aimed at reducing pollution from poultry waste and approved a new deal that called for more water-quality testing while agreeing not to institute any new enforcement actions or judicial proceedings against the industry. Pruitt also has faced sharp criticism from environmentalists for failing to take any action to help curb a dramatic spike in earthquake activity that scientists have linked to the underground disposal of oil and gas wastewater.
