Former Agriculture Commissioner Richie Farmer pleaded not guilty Thursday to federal charges that he misused more than $450,000 of state money and property during his eight years as Kentucky's top agriculture official. Farmer, a former University of Kentucky basketball player whose retired jersey hangs in Rupp Arena, appeared Thursday afternoon with his attorney, J. Guthrie True, at the federal courthouse in Lexington. A grand jury has charged Farmer, 43, with four counts of misappropriating property and money, and one count of soliciting property to influence agriculture department business.
