New York mayor to preside at same sex wedding on July 24

It will only be the third time that Bloomberg, who has been a staunch supporter of changing the law to allow same-sex couples to wed, has officiated at a wedding since taking office in 2002.

Jonathan Mintz, the city's consumer affairs commissioner, and John Feinblatt, a chief adviser to the mayor, will marry at Gracie Mansion in Manhattan.

"John and Jonathan have each done so much to make the City a better place, and together, they helped me see the issue of marriage equality in very clear terms," Bloomberg said in a statement provided through a spokesman. "This will be one of the biggest days of their lives, a day they've waited a long time to see, and I'm just honored to be a part of it."
