On September 11, 2017, the U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt sent a letter to Senator Sheldon Whitehouse (D-RI) in response to the request by Senator Whitehouse and four other Democratic Senators to explain Carl Icahn’s role in shaping the Renewable Fuel Standard (RFS) program. According to Pruitt, Icahn did not exercise excessive influence on the U.S. biofuels policy while acting as an advisor of President Trump.  The letter states that Icahn was one of many advisors that Trump met with during his confirmation and no assurances were made regarding any substantive issue, including the point of obligation.  Following an investigation into the e-mails of 39 of EPA’s senior leadership, EPA’s Office of Environmental Information (OEI) found no correspondence to or from Icahn or his company, CVR Energy, between February and August.  A spokesman for Senator Whitehouse stated that the letter was being reviewed “for accuracy and to determine whether additional steps are warranted.”
