No effect on internet gambling bill.
The most telling part of the indictment is the RICO charges "The racketeering conspiracy alleges that the defendants agreed to conduct an enterprise through a pattern of racketeering acts, including repeated mail fraud, wire fraud, operation of an illegal gambling business and money laundering"
I believe the Wire Act charges are somewhat incidental and the main thrust is to get them on fraud and racketeering. These are the charges that allow the Feds to seek forfeiture of $4.5 billion.
It is also significant that "In conjunction with the indictment, the United States has filed a civil complaint in federal court to obtain an order requiring BetonSports PLC to stop taking sports bets from the United States, and to return money held in wagering accounts to account holders in the United States.", although I don't see how the US has jurisdiction.
