The head of a major gambling industry group said Friday that he is hoping charges will be laid against operators of illegal sportsbooks and casinos shortly, a move that would send a severe message to entities still taking bets in the “gray” and “black” markets.

The Washington, D.C.-based American Gaming Association (AGA), whose members include the operators of brick-and-mortar casinos and online sports betting sites, has been continuously pushing lawmakers to crack down on illegal and unregulated wagering activities.

AGA President and CEO Bill Miller said during his remarks to the National Council of Legislators of Gaming States on Friday that their goal in the coming months is to obtain indictments.
