Gov. Mike DeWine said he’s taken a personal interest in enforcing state regulations for advertising by gambling companies, in his first comments on the subject since the launch of legal sports betting in the state on Sunday.

DeWine told reporters on Tuesday that he’s shared his concerns directly with the executive director of the Ohio Casino Control Commission, the state agency that regulates betting in Ohio, as well as with several members of the casino control commission’s board.

“The companies that are doing the massive advertising need to be aware that they’re being looked at very closely by the governor and the Casino Control Commission in regard to statements that they are making,” DeWine said.
