Hilary Swank, Debra Messing, Glenn Close

Celebrities such as Debra Messing, Glenn Close and Hilary Swank are very excited about President Barack Obama's support of same-sex marriage.

As the former star of NBC's Will & Grace (one of the first successful shows to portray openly gay characters), Messing was particularly moved by the President's statement.

"To have the President of the United States come out and openly support equal marriage rights... and [for Joe Biden] to say that Will & Grace has done more to educate the country about gays and lesbians —it's humbling. It makes me very emotional," she told TVGuide.com at Mariska Hargitay's Joyful Heart Foundation Gala in New York.
