The Washington, D.C. City Council voted, Tuesday, to allow same-sex couples to marry, sending the measure to Mayor Adrian Fenty who has pledged to sign it.
Despite the 11-2 vote, however, Congress has the final say over D.C.'s laws and traditional marriage supporters are vowing to get the bill overturned.
CBN News spoke with Brian Brown of the National Organization for Marriage for more on how D.C.'s gay marriage law could affect the rest of country. Click play for his comments following Paul Strand's report..
The vote is not surprising in a city government largely made up of liberal officials and a strong gay activist community.
That community was all cheers as the council voted to approve same-sex marriage for the District of Columbia.
"I speak to crowds often about the importance and significance of our Constitution, how it is an inspirational document," councilman David Catania said after the vote. "It presupposes that we are better than we are. And for the last 200-plus years we have made it our lives' work in this country to perfect and bring life to those words, even as forces of intolerance attempt to tether us to our past."
Still, opponents say they're not giving up.
"This is not over," said Bob King of Stand4Marriage. "They should not pay the toll before they get to the bridge or lock the barn before the horse gets out. We have just begun to fight God's war."
Backers of gay marriage say this has been a good year for them, with more states ruling in their favor, and now the District of Columbia.
But opponents say it's also been a good year for them.
Voters in the Maine threw out same-sex marriage after their legislature approved it. The New York legislature also decided against a measure along with the New Jersey legislature.
Many fear that if same-sex marriage is allowed in D.C., it could have national implications.
