The Center for Media and Democracy (CMD) has published thousands of emails obtained from the office of former Oklahoma Attorney General, Scott Pruitt, who was recently sworn in as the head of the U.S. Environmental Protection Agency (EPA) for the Trump administration.

Housed online in searchable form by CMD, the emails cover Pruitt's time spent as the Sooner State's lead legal advocate and in particular show a "close and friendly relationship between Scott Pruitt's office and the fossil fuel industry," CMD said in a press release. CMD was forced to go to court in Oklahoma to secure the release of the emails, which had sat in a queue for two years after the organization had filed an open records request.

Among other things, the emails show extensive communication with hydraulic fracturing ("fracking") giant Devon Energy, with Pruitt's office not only involved in discussions with Devon about energy-related issues like proposed U.S. Bureau of Land Management fracking rules, but also more tangential matters like how a proposed airline merger might affect Devon's international travel costs. They also show a close relationship with groups such as the Koch Industries-funded Americans for Prosperity and the Oklahoma Public Policy Council, the latter a member of the influential conservative State Policy Network.

On the U.S. Bureau of Land Management fracking rule, Pruitt's office solicited input from Devon, the Oklahoma City fracking company, which seemed to incorporate the feedback in the company's formal legal response. Pruitt's office was aiming to sue the U.S. Bureau of Land Management on the proposed rules, a case multiple states eventually won, getting indispensable aid in the effort from the Interstate Oil and Gas Compact Commission.

"Any suggestions?" Pruitt's office wrote in a May 1, 2013 email to a Devon vice president. Attachments missing from the Freedom of Information Act response make it unclear to what extent edits suggested by Devon were actually inserted into the Attorney General's correspondence, although Pruitt's deputy later wrote "thanks for all your help on this."

In two other emails dated May 1, 2013, a Devon Energy director replied with suggested changes to Pruitt's office. The next day, Pruitt's office sent the final draft of the letter to Devon, which replied, "I'm glad the Devon team could help and thanks for all of your work on this."

This batch of emails was not among those published by the New York Times as a part of its investigation into the correspondence Pruitt and other Republican state-level Attorneys General had with energy companies, which revealed that Devon had ghostwritten letters which Pruitt's office sent to federal officials and agencies.
