A bipartisan group from Congress has called upon the Department of Justice to increase scrutiny and prosecution of illegal offshore sportsbooks at the same time that regulated sports wagering operators continue to expand their reach across the U.S.

The group includes 28 representatives from 13 states, ranging from mature sports wagering markets in Nevada and New Jersey to those which will launch in 2023 (Ohio) and those that have yet to legalize, including California and Texas. Sports wagering, when including states that offer tribal gaming, is legal in 35 states and the District of Columbia.
