Members of the Obama administration are coming out in support of gay marriage.
Vice President Joe Biden said he is "absolutely comfortable" with equal rights for married gay couples.
"I am absolutely comfortable with the fact that men marrying men, women marrying women and heterosexual men and women marrying one another are entitled to the same exact rights, all the civil rights, all the civil liberties," Biden told NBC's "Meet the Press" in an interview broadcast Sunday.
Biden, who is Roman Catholic, said that marriage is about being loyal to someone you love, whether that marriage is between a man and a woman, two men or two women.
After the vice president's comments, Education Secretary Arne Duncan also voiced his support of same-sex marriage to MSNBC.
Later, White House Press Secretary Jay Carney touted President Barack Obama's record of "extremely aggressive" support for gay rights.
"The vice president, what he said about the protection of rights of citizens is completely consistent with the president's position on this issue," Carney told reporters.
"There's a long, long list of the actions that this administration has taken on behalf of LGBT citizens in this country," he continued. "And that's a record that the president's very proud of."
Following Biden's interview, gay rights advocates commended him for his support.
''I'm grateful that the vice president of the United States is now publicly supporting marriage equality and I hope very soon the president and the rest of our leaders, Republicans and Democrats in Congress, will fall in line with the vice president," said Chad Griffin, a gay rights supporter and a member of the Obama campaign's national finance committee.
President Obama has said he opposes gay marriage but that his views on the issue are "evolving."
