The case of a 6-month-old Lansing girl who was removed from her parents after a complaint involving medical marijuana has become a rallying point for groups aligned behind the state's 5-year-old medical marijuana law.

Holding placards and chanting, "Free Bree," dozens of people gathered outside the Grand Tower on Tuesday to protest the state Department of Human Services' efforts to remove Brielle "Bree" Green from parents Gordon "Steve" and Maria Green.
