Barr took a lead in legislative debate concerning same-sex marriage . He authored and sponsored the Defense of Marriage Act , a law enacted in 1996 which states that only marriages that are between a man and a woman can be federally recognized , and individual states may choose not to recognize a same-sex marriage performed in another state . At the 2008 Libertarian National Convention , he apologized for the part of the Defense of Marriage Act which prevents the federal government from recognizing same-sex marriages
