Kentucky Senate President David Williams is proposing a state constitutional amendment to limit any expansion of gambling unless it is done by amending the constitution.

Senate Republicans met Tuesday with Kentucky horse industry leaders to discuss the future of gambling in the state.

Georgetown Republican Sen. Damon Thayer says he's also offering a constitutional amendment that would allow video gambling machines in the seven counties that already have horse racing tracks.

Horse industry reprsentatives for years have been pushing for an expansion of gambling in Kentucky, and Gov. Steve Beshear has supported the idea.

Kentucky Thoroughbreds Association President Don Robinson on Tuesday said Thayer's and Williams' plans are "too little, too late." Robinson says the horse industry supports casino gambling at race tracks, the same plan that cleared the House earlier this year.
