Democrats in the Michigan Senate have declined to give Republicans enough votes to make changes sought to the voter-approved medical marijuana law.
The Senate late Thursday and early Friday failed to pass bills by a necessary three-fourths vote requiring patients to get a photo identification card and clarify the type of doctor-patient relationship needed before marijuana use could be certified.
The chamber approved bills dealing with criminal guidelines for patients or caregivers selling marijuana to unauthorized users and transporting open medical marijuana in vehicles.
Republican Sen. Rick Jones says it's strange Democrats would block legislation passed in the House with bipartisan support.
Senate Democratic spokesman Robert McCann says "Republicans are trying to go around the will of the people as we've seen them do far too often."
