Online betting scandals are getting worse. Will lawmakers intervene?

As scandals continue to plague popular online betting platforms, calls within Congress to intervene are getting louder.

A series of controversies in April - from political candidates profiting from their own campaigns to a soldier's alleged bet on a major military operation - prompted a unanimous April 30 decision to change the Senate's rules. Senators and their staff members were banned from trading on prediction markets, where people can buy and sell bets online on future events.

Sen. John Curtis, R-Utah, vowed that it was just the beginning of a new wave of federal scrutiny. Next on the legislative agenda, he said, would be prohibiting all government officials from using insider information to bet on prediction market contracts.
