The bill was crafted by Sensator Pat Roberts (R-KS) and Debbie Stabenow (D-MI).[1] The "GMO labeling bill"[6] was introduced on 17 March 2015 by its sponsor, Sen. Roger F. Wicker (R-MS),[3] cosponsored by Sen. Dan Sullivan (R-AK), and passed Senate and House in June 2016. The law overturned relevant state laws such as Vermont's GMO labeling law that had called for strict and transparent GMO food labeling in Vermont after July 1, 2016.[7]
