U.S. Democratic lawmakers asked Environmental Protection Agency head Scott Pruitt on Wednesday to disclose procedures to prevent billionaire Carl Icahn from influencing U.S. biofuels policy for personal gain.
The letter is the latest in a string of missives from Democrats concerned about Icahn's dual role as a special adviser to President Donald Trump on regulation and as a major investor
in heavily regulated industries.
Icahn has an 82 percent stake in oil refiner CVR Energy Inc. He has also recommended the White House change the biofuels program that would reduce costs to CVR and other refining companies.
