DOMA Killer Edith Windsor Celebrating With ... Dance Party She will also be grand marshal of NYC's Gay Pride Parade Sunday By John Johnson, Newser Staff Posted Jun 27, 2013 12:40 PM CDT 26 comments Comments Edith Windsor, left, the plaintiff in the DOMA case, arrives at the LGBT Center in New York Wednesday. (AP Photo/Richard Drew) (Newser) – It was 83-year-old Edith Windsor's case that ended up killing the Defense of Marriage Act, and Windsor will celebrate Sunday by acting as grand marshal of the Gay Pride Parade in Manhattan. But another special celebration precedes that on Saturday night: a dance party with friends, reports People. The significance? "When she met (her late wife) Thea Spyer nearly 50 years ago, they danced so long Edie wore a hole in her sock," says a friend. Windsor and Spyer eventually married in Canada in 2007, and Spyer died two years later. When Windsor had to pay $363,000 in federal estate taxes—because the US didn't recognize the marriage—she sued. Now she's getting her money back. And after the ruling yesterday, she was at the apartment of attorney Roberta Kaplan when the phone rang, reports the New Yorker. "Hello, who am I talking to?” Windsor said. “Oh, Barack Obama? I wanted to thank you. I think your coming out for us made such a difference throughout the country.” It wasn't the only phone call Obama made yesterday.
