Thousands of pages of newly released emails reveal how EPA Administrator Scott Pruitt closely collaborated with oil, coal and gas companies backed by the Koch brothers to roll back environmental regulations during his time as Oklahoma attorney general. The documents were released just days after Pruitt was sworn in as the new head of the EPA, the agency tasked with curtailing pollution and safeguarding public health. Last week, Senate Democrats unsuccessfully attempted to postpone Pruitt’s final confirmation until the emails were released, but Republicans pressed forward and confirmed him in a 52-46 vote, largely along party lines. As Oklahoma attorney general, Pruitt sued the EPA 14 times. The trove of new documents shows how energy companies drafted language for Pruitt’s Attorney General’s Office to use to sue the EPA over environmental regulations. We speak to Lisa Graves, executive director of the Center for Media and Democracy, which successfully sued for the emails to be released.
