An Illinois state lawmaker is calling for a first of its kind crackdown on a virtual invasive species.

FOX's Jeff Monosso in Chicago explains:

Never mind invasive weeds that have long threatened the dunes here along Chicago's lakefront, it's now the invasion of 'Pokémon GO' characters that's had players via their smart phones, trampling through native and protective grassland, says state rep. Kelly Cassidy, who's sponsoring a bill that would require app developers to remove locations in augmented reality games within two days of a request or face a daily fine of $100.

Developers of 'Pokémon GO' have removed the Pokestop as it's called, but Cassidy said it took several calls and the introduction of her bill.
