DENVER -- Colorado's attorney general has asked the U.S. Supreme Court to throw out a lawsuit neighboring states filed against Colorado.
Nebraska and Oklahoma sued to overturn Amendment 64. That's the law voters approved allowing the sale of recreational marijuana.
Officials from those two states say pot from Colorado is flowing over the borders into their states.
The Supreme Court still has to decide whether it will hear the case.
Attorney General Cynthia Coffman plans to defend the state law on marijuana whenever necessary.
