Former Kentucky Agriculture Commissioner Richie Farmer may be on trial for three weeks in Frankfort’s federal courthouse, prosecutors said Thursday during Farmer’s arraignment. In addition, U.S. Magistrate Judge Robert Wier told Farmer he could not take a planned vacation to Mexico and must remain in the state until his trial begins. Farmer, who played on the 1992 University of Kentucky basketball squad dubbed “The Unforgettables,” pleaded not guilty to four counts of misusing state resources and one charge of accepting property in exchange for a Department of Agriculture grant.
