Yesterday, a group of Democrats in the House of Representatives officially proposed legislation to repeal the federal Defense of Marriage Act. The bill would affect both parts of the act, the definition of marriage for federal-law purposes and the specification that the Constitution’s Full Faith and Credit Clause does not require one state to recognize another state’s same-sex marriages. The administration has been on record in support of repeal, but this specific bill seems unlikely to make real headway in the short term.
