Vice President Joe Biden has endorsed gay marriage.

Appearing Sunday on NBC's Meet the Press, Biden told host David Gregory that he is “absolutely comfortable with the fact that men marrying men, women marrying women.” He then added, “The president sets the policy.”

An indication that Biden was shifting towards acceptance could be found in his 2010 remarks on the ABC morning talk show Good Morning America, where he compared gay marriage to repeal of “Don't Ask, Don't Tell,” the now scrapped policy which banned gay and bisexual troops from serving openly.

“Well, I think the country is evolving,” Biden told George Stephanopoulos, “I think there is an inevitability for a national consensus on gay marriage. That is my view.”

“I remember the first time [Obama] met with the Joint Chiefs – I was with him. He said, 'Gentlemen, I want you to prepare now. I want to end 'Don't Ask, Don't Tell.' And so he prepared the ground so that it is as widely accepted as it is today by the military. And I think the same thing is happening across the country with regard to the issue of marriage,” he said.

In 2008, Biden, whose home state, Delaware, recognizes gay couples with civil unions, was squarely opposed to marriage equality.

While the vice president said that he believed “there should be no civil rights distinction, none whatsoever, between a committed gay couple and a committed heterosexual couple,” he also added that neither he nor Barack Obama “support redefining from a civil side what constitutes marriage. We do not support that.”
