WASHINGTON (CNN) - The Washington D.C. City Council voted 12-1 Tuesday to recognize same-sex marriages from states that allow those unions.
Mayor Adrian Fenty has indicated he will sign the measure. It will then become law after a mandatory 30-day congressional review period if Congress fails to overturn the measure.
Former Mayor Marion Barry cast the lone dissenting vote.
While the council voted to recognize same-sex marriages, those marriages are not currently allowed in the district.
Three states - Massachusetts, Connecticut, and Iowa - currently allow same-sex marriages. A law passed by Vermont legislators that makes gay and lesbian marriages legal takes affect in September. New Hampshire lawmakers are close to passing a similar bill.
Fifty-four percent of adults questioned in an April 23-26 nationwide CNN/Opinion Research Corporation poll said that marriages between gay or lesbian couples should not be recognized as valid, with 44 percent suggesting they should be considered legal.
