Per a report from Kotaku, Senator Josh Hawley (R-MO) has announced “The Protecting Children from Abusive Games Act," a bill that would ban loot boxes and pay-to-win microtransactions in “games played by minors.”
I can’t seem to find the the actual bill itself or a statement from the Senator but this should be… interesting.
edit: The Kansas City Star has an article that goes in to slightly more detail on the subject.
edit 2: Kotaku has updated there piece with the following:
UPDATE (12:18pm): The Entertainment Software Association, the video game industry lobbyist group, sent over a statement shortly after this bill was introduced: “Numerous countries, including Ireland, Germany, Sweden, Denmark, Australia, New Zealand, and the United Kingdom, determined that loot boxes do not constitute gambling. We look forward to sharing with the senator the tools and information the industry already provides that keeps the control of in-game spending in parents’ hands. Parents already have the ability to limit or prohibit in-game purchases with easy to use parental controls.”
