WASHINGTON — After an emotional debate, the D.C. Council gave final approval today to legislation that recognizes same-sex marriages performed elsewhere.

The vote is considered the first step toward eventually allowing gay marriages to be performed in Washington. Congress, which has final say over the city's laws, will get 30 days to review the bill assuming Democratic Mayor Adrian Fenty, a supporter, signs it.

If Congress takes no action, the bill will become law automatically. President Barack Obama and congressional leaders have not signaled where they stand on the D.C. bill. Obama generally supports civil unions but has said marriage is between a man and a woman.

"The march toward equality is coming to this country, and you can either be a part of it or stand in the way," said David Catania, one of two openly gay D.C. Council members.

Vermont, Connecticut, Massachusetts and Iowa already allow gay marriage and lawmakers in several other states are considering whether to do the same. New York recognizes gay marriages performed in other states.

The D.C. Council vote was 12-to-1, with former Mayor Marion Barry casting the lone opposing vote. Barry, a longtime supporter of the gay community, called it an "agonizing and difficult decision" that he made after praying and consulting with his constituents and the religious community.
