LOUISVILLE, Ky. (AP) - Kentucky's attorney general has issued civil subpoenas to Marathon Oil Co., as he explores a possible lawsuit against the petroleum giant.
Also, several Kentucky officials have asked the Federal Trade Commission and the U.S. Department of Justice's Antitrust division to review the 1997 merger of Marathon and Ashland Oil to gauge its effect on gas prices in Louisville and the rest of Kentucky.
The moves Thursday night came after a summer gas price spike in Kentucky, which left drivers paying as much as 18 cents more per gallon in Louisville than in other parts of the state.
Marathon Oil has 45 days to respond to the subpoenas.
Attorney General Jack Conway said he'll decide whether to sue Marathon after studying the company's response.
"It is squarely on Marathon," Conway said. "If our consumers are being treated in an inappropriate way ... maybe there's something I can do."
