In September 2015, Beavers proposed bill SB1437, known as the Tennessee Natural Marriage Defense Act, to ban same-sex marriage in Tennessee despite the Supreme Court's decision to legalize it. Her colleague in the House, Mark Pody, proposed a similar bill. After just 90 minutes of testimony, the House Civil Justice Committee rejected that bill. Had the bill passed, it would have cost Tennessee upwards of $8.5 billion in federal funding, in addition to millions of dollars in legal bills, mostly impacting programs that support Tennessee families in need such as the Supplemental Nutrition Assistance Program (SNAP), and Temporary Assistance for Needy Families (TANF).
