Pennsylvania, New Jersey and Nevada have legalized online gambling and allow poker players to play online across the states. Pennsylvania began online gambling in 2017.

In a letter Tuesday, New Jersey Attorney General Gurbir Grewal said online gambling produces more than $350 million in annual revenue in the state.
Pennsylvania Attorney General Josh Shapiro joined Grewal in opposing the new opinion.
Grewal also filed a public records request for communications between the DOJ and casino groups opposed to online gambling.
