New York City Council Speaker Christine Quinn says being denied federal recognition of her marriage is “painful.”

Quinn, who leads among Democrats in her bid for mayor, in May married her longtime partner, lawyer Kim Catullo.

In an appearance on CNN to discuss a Supreme Court case challenging the Defense of Marriage Act (DOMA), Quinn said gay people are full citizens and praised the woman at the center of the case, Edith Windsor.

“Waking up everyday in a country where your sexual orientation puts you in a position where you have fewer rights than somebody else is actually a very painful thing,” Quinn said. “I mean, LGBT Americans are full citizens. We're full contributing parts of this country. And all we want is the same rights and responsibilities as everybody else.”

When Windsor's wife Thea Spyer got sick “Edie took care of her until she died. And then after that tragic death the federal government basically sent Edie a letter saying, 'You are less than [the] heterosexual Americans that you know.' That's horrible. It's just wrong. And I'm so excited that this issue has gotten all the way to the Supreme Court.” (The video is embedded on this page. Visit our video library for more videos.)
