Rick Santorum has reiterated his opposition to gay marriage, telling CNN's Piers Morgan that he would as president outlaw the institution.

Appearing Friday on Morgan's Piers Morgan Tonight, Santorum insisted that from the “standpoint of faith and reason” restricting marriage to heterosexual couples “makes all the sense in the world.”

“Having said that, I think it's important to understand that you respect everyone and you respect their rights to be able to live their life in the way that they want to live it,” Santorum said.

When Morgan asked, “So when you say you respect their rights, isn't their legal right in New York now to get marriage?” Santorum answered: “Well, it's a law. But it's not a natural right. I mean, it's a law. There are lots of laws that are not rights … I would say it's a privilege.”

“I would change the law to make a uniform definition of marriage in this country,” he added.

“Are you going to try and make it illegal for gay people to get married?” Morgan asked.

“All I would say is that marriage has been voted on 32 times in this country in 32 states, from Maine to California, and 32 times the people of this country have said that marriage is between a man and a woman and the public should have a say about this,” Santorum answered.
