Vice President Joe Biden gave a nod to same-sex marriage on Sunday's Meet the Press and credited Will & Grace for changing public opinion.

While Biden declined to comment if President Barack Obama will change his position from supporting civil unions to same-sex marriage if they win a second term, Biden said he's "absolutely comfortable" with it and that the issue is "evolving." He then cited Will & Grace — the most successful prime-time show with a gay lead.

"When things really began to change is when the social culture changes," Biden said. "I think Will & Grace

probably did more to educate the American public than almost anybody's ever done so far. People fear that which is different. Now they're beginning to understand."Shortly after Biden's interview, Will & Grace star Debra Messing tweeted, "I'm thrilled Biden has come out in support of gay marriage and am beyond proud of what he said [about Will & Grace] #PROUD. Thank you Mr. Vice President for yer [sic] support and yer [sic] words about W&G. #humbled."

Eric McCormack later responded by tweeting: "Three cheers for VP Joe Biden! Fantastic interview. Now who ELSE is gonna step up? "
