Maine’s Gambling Control Board has ruled that the Oxford Casino won’t be asked to apply for a new operator’s license if a sale to the company that owns the home of the Kentucky Derby is approved. Oxford Casino owners announced the $160 million sale in March to Churchill Downs Incorporated Properties, the parent company of Churchill Downs Racetrack. Oxford Casino vice president and general manager Jack Sours told the Sun Journal, after Tuesday’s board meeting that the sale process is still under way. Director Patrick Fleming says the board is currently running a background investigation on Louisville, Ky.-based Churchill Downs. Churchill Downs is expected to present its plans to the board in July. The western Maine casino has 814 slot machines and 22 table games and employs 420 people.
