Biden: 'Men marrying men' should have equal rights

Vice President Joe Biden on Sunday endorsed equal rights for married gay men and lesbians -- and President Barack Obama's top aide said that the president had "precisely" the same position.

"The good news is that as more and more Americans come to understand what this is all about is a simple proposition," Biden told NBC's David Gregory. "Who do you love? Who do you love and will you be loyal to the person you love? And that’s what people are finding out what all marriages at their root are about, whether they're marriages of gay men or lesbians or heterosexuals."

"The president sets the policy," he acknowledged, but "I am absolutely comfortable with the fact that men marrying men, women marrying women and heterosexual men marrying women are entitled to the same exact rights. All the civil rights, all the civil liberties. And quite frankly I don’t see much of a distinction beyond that."

Biden added that he didn't know if President Barack Obama would support full same sex marriage rights in his second term.

"I don't know the answer to that," the vice president admitted. "People fear that which is different and now they're beginning to understand."

Obama campaign senior adviser David Axelrod quickly took to Twitter to say that his boss had the exact same position on marriage equality.

"What VP said-that all married couples should have exactly the same legal rights-is precisely POTUS's position," Axelrod tweeted.
