Clay Aiken appeared on "Face the Nation" on May 13 to talk about same-sex marriage and its importance in the upcoming 2012 presidential election.
The former "American Idol" contestant, who announced he is gay in 2008, joined the panel to discuss the issue and a recent amendment passed in his home state of North Carolina, which defined marriage as a union between a man and a woman.
"I think between 2003 and today, as we've seen with gay marriage polling, we've seen minds changing. We've seen more people becoming more open and understanding of homosexuality," he told host Bob Schieffer. Aiken's appearance can be seen below.
Aiken came in second place on "American Idol" in 2003 and has since gone on to release six studio albums, become a UNICEF National Ambassador and appeared on Broadway in "Monty Python's Spamalot." In 2008 he also welcomed a son with his friend Jaymes Foster, the sister of record producer David Foster. He is currently a contestant on season five of "The Celebrity Apprentice" and is in the final three alongside Arsenio Hall and Aubrey O'Day.
Aiken responded to a comment made by Tony Perkins, the president of a conservative Christian organization called the Family Research Council, who said there was a difference between comparing the previous ban on interracial marriage and same-sex marriage.
"When you look at interracial marriage, that was wrong because there was no reason to be opposed to that because you had two people who met the definition of marriage between a man and a woman," Perkins said. "And that's consistent with natural law, which our civil rights are based on."
Aiken said, "Obviously we've got people who make the argument that interracial relationships -- back in the 70s people made the same arguments against interracial relationships as they're making against same-sex marriages today."
He added, "So I really feel that in the next 20 years, we're going to look back on this and be sort of ashamed that we were against this, just as we are ashamed today that we didn't let people of different races get married."
Last week in an interview with ABC News' Robin Roberts, President Barack Obama became the first sitting president to openly support same-sex marriage. ABC is the parent company of OnTheRedCarpet.com.
When asked by Schieffer if President Obama's support of same-sex marriage meant that the singer would help President Obama in the upcoming election, Aiken revealed that he voted for President Obama in the 2008 election.
"I voted for President Obama last time and I think all gay men and women are energized to vote for President Obama now," he said. "So I'll definitely be helping how I can."
