Scott Pruitt left the EPA mired in scandal. Now he is lobbying Indiana lawmakers.

Scott Pruitt, the embattled former administrator of the U.S. Environmental Protection Agency, registered Thursday as a lobbyist with state regulators. Pruitt's filings with the Indiana Lobby Registration Commission identify him as a self-employed consultant and list RailPoint Solutions LLC as his sole client. His lobbying topics include "energy" and "natural resources."It's unclear what, exactly, Pruitt is working on or who he is meeting with at the Statehouse, but he has ties to the Indiana coal industry. IndyStar's attempts to reach him Thursday afternoon were unsuccessful.RailPoint Solutions does not appear to have a web address, nor is a company by that name registered to do business in Indiana. A search of Delaware business records, however, shows an incorporation date of Jan. 22.
