Mich. Comp. Laws § 431.324

Sec. 24. A person licensed under this act shall not knowingly permit the dissemination of racing information that might be of benefit to the operator of an illegal handbook or other illegal gambling enterprise, including the changes in odds which may take place during the period of wagering in advance of each race. This section does not prevent the accredited representatives of newspapers, turf publications, newspaper press services, radio and television networks and stations, and other news and sports reporting media from promptly reporting from the racetrack the results of races, payoff prices on winning tickets, entries, claims, and other information concerning the actual running of races and training activities.
