Way back before Donald Trump was elected US president, he made his support of online gambling rather clear. Despite that, he may be preparing to approve RAWA.
Restoration of America’s Wire Act (RAWA in short), the first iteration of which surfaced as 1961's Wire Act, aims to prohibit all forms of communication to be used for the purposes of gambling, which includes the internet. The bill seeks to nullify 2011's Department of Justice opinion, which stated that the Wire Act is only applicable to sports betting.
If RAWA passes, Delaware, New Jersey, and Nevada would be in violation of the law. If this is the case, then lotteries, horse racing, and fantasy sports would be the only remaining legal forms of gambling.
Though Trump doesn't have an issue with online gambling in general, he realizes that this is a personal project for Lindsay Graham, Jason Chaffetz, and Marco Rubio, so signing RAWA would mean doing a huge favor for his Republican colleagues.
When Delaware tried to introduce sports betting, which PASPA allowed them to do, the courts only gave them permission to offer parlay tickets on NFL football rather than a broad array of sports betting options.
If online casino roulette gets banned together with other casino games such as blackjack, craps, and slots, there is a good chance that Sheldon Adelson, the casino magnate who contributed millions to various Republican campaigns, will agree to the carve out. Since Adelson has been pushing for the changes since the beginning, it is likely that the bill sponsors will agree to follow his stance.
The casino owners will likely appeal the decision to rewrite the Wire Act, and California seems to be the wild card here. Though the state has mostly voted against Trump, it is almost a given that he doesn't want to upset them, since California is a valuable business asset for him.
In any case, the future of gambling in the US still remains uncertain.
