Attorneys general in at least a dozen states are working with energy companies and other corporate interests, which in turn are providing them with record amounts of money for their political campaigns, including at least $16 million this year. The Times reported previously how individual attorneys general have shut down investigations, changed policies or agreed to more corporate-friendly settlement terms [for] campaign benefactors. But the attorneys general are also working collectively. Out of public view, corporate representatives and attorneys general are coordinating legal strategy and other efforts to fight federal regulations, according to a review of thousands of emails and court documents and dozens of interviews. Attorney General Scott Pruitt of Oklahoma [used his post] to help start what he and allies called the Rule of Law campaign. That campaign, in which attorneys general band together to operate like a large national law firm, has been used to back lawsuits and other challenges against the Obama administration on environmental issues, the Affordable Care Act and securities regulation. The most recent target is the president's executive action on immigration. Coordination between the corporations and teams of attorneys general involved in the Rule of Law effort also involves actual litigation to try to clear roadblocks to energy projects, documents show.
