The Senate narrowly confirmed Scott Pruitt as the new Environmental Protection Agency chief on Friday, despite Democrats calls to delay the vote until the release of a new trove of documents detailing the Oklahoma attorney generals relationship with oil and gas companies.

The 52-46 vote divided the Senate along party lines, with just two Democrats Sens. Joe Manchin (W.V.) and Heidi Heitkamp (N.D.), who are up for re-election in states with big fossil fuel industries voting to confirm Pruitt. Sens. John McCain (R-Ariz.) and Joe Donnelly (D-Ind.) did not vote.

Pruitt won the Senates approval the day after Judge Aletia Haynes Timmons of the District Court of Oklahoma County ordered his office to turn over more than 2,500 emails and other documents by Tuesday.

The watchdog group Center for Media and Democracy, represented by lawyers from the American Civil Liberties Union, filed a lawsuit against Pruitt earlier this month, alleging his office had violated Oklahomas open records law .

The lawsuit claims that Pruitt, who has served as Oklahomas top cop since 2011, failed to respond to nine open records requests seeking communications between his office and major fossil fuel players, including Koch Industries, Peabody Energy and the National Coal Council. The requests were filed as early as January 2015.

Scott Pruitt is the worst pick ever confirmed to lead the EPA. Hes being sent there to hobble the agency we depend on to protect our health and environment, Rhea Suh, president of the environmental nonprofit Natural Resources Defense Council, said in a statement. All the worse, Senate Republicans forced the confirmation vote before the public can know the truth about Pruitts ties to industrial polluters.

Nearly 800 former EPA staffers signed a letter this week urging senators to vote against Pruitt. Democratic senators moved to delay the vote on Friday after live-streaming sometimes heated speeches opposing Pruitt on Facebook.
