Gov. Pat Quinn says that any state revenue from gambling should go toward education.
Quinn delivered a budget address on Wednesday that includes $400 million in cuts for schools.
But Quinn says any new gambling legislation must have ethical protections.
Quinn has vetoed two gambling expansions that lawmakers have sent him. Both bills proposed nearly half a dozen new casinos in the state, including one in Chicago.
Quinn is calling for a ban on contributions from the gambling industry, but lawmakers haven't been thrilled about it.
The Senate's executive committee was scheduled to look at another possible gambling expansion later Wednesday.
