Vice President Joe Biden made comments in support of gay marriage two days after President Obama gave the institution a lukewarm cheer.

The self-described “fierce” gay rights advocate refused to endorse marriage for gay and lesbian couples shortly after he signed a landmark gay rights bill that repeals “Don't Ask, Don't Tell,” the 1993 law that bans gay and bisexual troops from serving openly.

“My feelings about this are constantly evolving – I struggle with this,” Obama told reporters on Wednesday. “I have friends, I have people who work for me who are in powerful, strong, long-lasting gay or lesbian unions. And they are extraordinary people.”

“At this point, what I've said is that my base line is a strong civil union that provides them the protections and the legal rights that married couples have. And I think that's the right thing to do. But I recognize that from their perspective it is not enough. And I think this is something we're going to continue to debate. And I personally am going to continue to wrestle with going forward.”

Biden, on the other hand, came close to endorsing the institution, saying it was “inevitable.”

Appearing Friday on ABC's morning talk show Good Morning America, Biden compared gay marriage to the issue of the military's gay ban.

“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 he [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 added. (The video is embedded in the right panel of this page.)
