We've just learned that the supreme court justices are to take on cases related to the 1996 Defense of Marriage Act, and Proposition 8, California's 2008 measure banning same-sex marriage. It is a big moment.
I've just had a quick word with Edith Windsor, who is delighted at the news the supreme court has decided to take on her case.
"I feel delirious with joy; I think it's wonderful," she said. "I think it's the beginning of justice like I imagined in fourth grade civics. I'm thrilled at how it's gone."
Windsor said her wife Thea Spyer, who died in 2009, would be proud of the achievement.
"I think she'd be so proud and happy and just so pleased at how far we have come. It's a culmination of an engagement that happened between us in 1967 when we didn't dream that we'd be able to marry."
Windsor, a former IT worker, met Spyer in 1965. They became engaged in 1967 and finally married in in 2007. Spyer died in 2009 after battling multiple sclerosis for many years.
"I think Doma is wrong for all of the various ways in which it discriminates against same sex married couples and against gays all together," Windsor said.
"It's enormously satisfying and fulfilling and exciting to be where we are now."
Windsor said she was confident of the supreme court ruling in her favour.
"I really believe in the supreme court. First of all, I'm the youngest in my family and justice matters a lot – the littlest one gets pushed around a lot. And I trust the supreme court, I trust the constitution – so I feel a certain confidence that we'll win."
