It hasn't become a major issue in the presidential campaign, but the debate over same sex marriage continues to play out in the courts, and at the ballot box.
Today, lawyers for an 83-year-old woman are arguing a case in a Federal appeals court in New York that challenges the Defense of Marriage Act, or DOMA.
The law was passed by Congress in 1996, and signed into law by Bill Clinton. It denies federal recognition of same-sex marriage, and it gives individual states the right to refuse to recognize these marriages.
