Democrats in the House and Senate this week introduced a bill that would repeal the 1996 Defense of Marriage Act. Lawmakers point to a poll finding that a majority of Americans now oppose the law. In the House, the bill was sponsored by all four openly gay U.S. representatives, along with Reps. Jerry Nadler and John Conyers. A companion bill in the Senate was introduced by Democratic Sens. Dianne Feinstein, Kirsten Gillibrand and Patrick Leahy. "Nobody should think this is easy. It's not easy. ... Whether it takes one year or two years or three years or four years, we are committed to it," Feinstein said.
