PORTLAND, Ore. (AP) — An Oregon resident has filed a class-action lawsuit against two daily fantasy sports sites, claiming the businesses are operating illegal online sports betting.

The Oregonian reports that Polk County resident Brandon Peck filed the suit in federal court in Portland Monday. He filed it on behalf of himself and more than 100 Oregon players who lost money in the past three years while placing bets through DraftKings and FanDuel.

The lawsuit asks the court to halt the sites' operations and have each business pay players back double the amount they lost.

More than 30 class-action suits against daily fantasy sports websites have been filed in more than 10 states.

The companies have argued that fantasy sports aren't gambling but a game of skill. That exempts them from a federal law prohibiting online gambling.
