Freedom to Marry, one of the country's largest marriage equality advocates, has gathered mayors from across the United States to unify their support for same-sex marriage.

Houston's Annise Parker, Chicago's Rahm Emanuel, New York's Michael Bloomberg, Los Angeles' Antonio Villaraigosa and Boston's Thomas Menino are among the mayors joining together with Freedom to Marry to "expand public and political support for ending the exclusion of same-sex couples from marriage."

Noticeably absent from the list of mayors is Atlanta's Mayor Kasim Reed.

While campaigning in 2010, Reed was criticized by Atlanta's LGBT community for his personal opposition to same-sex unions. At a townhall-style meeting in November centered on the 2009 Atlanta Eagle raid, Reed refused to answer whether or not his views on marriage equality have changed since his campaign to become the city's mayor, leading many to believe that his position has remain unchanged.

Freedom to Marry plans to hold a press conference in Washington, D.C., on Friday, Jan. 20.
