RIVER FALLS, Wis. (AP) -- A River Falls alderman is facing drug charges.

Twenty-nine-year-old Robert Hughes was charged with illegally possessing marijuana, prescription pills and drug paraphernalia after police executed a search warrant at his town house.

Officers got a warrant after an officer delivered a City Council agenda to Hughes' home and said there was a strong odor of marijuana coming from the house.

Hughes says he has a prescription for one of the drugs found by police. Hughes' roommate, Daniel Gardner, has also been charged with drug possession.

The River Falls Journal says Hughes led a petition drive that put a medical-marijuana use petition on the ballot in River Falls last November. Voters approved the advisory referendum.
