In a final vote by a margin of 12-1, the lone dissenting vote cast by former D.C. Mayor Marion Barry, the city council has voted to recognize same-sex marriages preformed in other states.

This was the second vote of the morning. The first vote was a unanimous 13-0 until Barry realized what he had voted for and wanted a do-over.

If Congress fails to overturn the vote within 30 days, council member David Catania will introduce a separate bill legalizing same-sex marriage in the district later this year.
