U.S. Rep. Barney Frank has tied the knot with his longtime partner in a ceremony officiated by Massachusetts Gov. Deval Patrick.

Frank becomes the first active member of the U.S. Congress to marry a spouse of the same gender.

Frank spokesman Harry Gural says the 72-year-old congressman married 42-year-old Jim Ready in a Saturday evening wedding at the Boston Marriott hotel in Newton. Gural says more than 300 friends, family and colleagues attended.

According to The New York Times, Congresswoman Nancy Pelosi “stayed late — and swayed on the dance floor to It’s Raining Men.”

Frank, a Democrat who is retiring after more than three decades in office, represents the 4th Congressional District in southeastern Massachusetts.

Ready, of Ogunquit, Maine, has a small business doing custom awnings, carpentry, painting, welding and other general handyman services. He’s also a photographer.

Frank sat down with Current’s Bill Press just days after the wedding and noted that some Republicans have expressed congratulations on the nuptials, but that most of the GOP has “ignored” it. Frank remarked that this was a good thing—”there have been no negative comments.”
