One of the country's largest coal companies contributed $50,000 to a political action committee supporting Scott Pruitt in August, just as the company and the Oklahoma attorney general prepared for a key court appearance in their challenge to U.S. EPA's sweeping restrictions on power plants. Murray Energy Corp., the Ohio-based mine owner, will be able to make a similar contribution this year, legal experts say, even if the Senate confirms Pruitt, a Republican, to run EPA. The practical impact: Pruitt's Super PAC, Liberty 2.0, can keep raising money from the corporate interests he is charged with regulating.
