The ceremony will be the first same-sex marriage in the Wilson Building.
Wedding bells rang today at the John A. Wilson Building.
At noon Mayor Vincent Gray officiated the wedding ceremony of Rob Robertson and Carlos Taylor. According to an administration official, Robertson and Taylor, both D.C. residents, were introduced to Gray by Peter Rosenstein, a prominent gay activist and mayoral ally.
"The mayor was partly responsible for getting marriage equality in D.C., so I thought this would be a nice follow-up," says Rosenstein.
Same-sex marriage has been legal in D.C. since 2010. In August Gray signed a bill expanding the list of people authorized to solemnize marriages in the city, including the mayor and members of the D.C. Council.
In August Supreme Court Justice Ruth Bader Ginsburg officiated a same-sex marriage in D.C.
