Florida Senator Marco Rubio has come out against a federal constitutional amendment banning gay marriage.

Rubio is considered a rising star in the Republican Party. And his star will rise higher next week when he delivers the GOP response to President Barack Obama's State of the Union address. Rubio's plan to speak in English and Spanish has created controversy.

The 41-year-old first-term senator appears on the cover of Time magazine under the headline “The Republican Savior: How Marco Rubio became the new voice of the GOP.”

Last year, Rubio joined former Arkansas Governor Mike Huckabee in helping fellow Republican Mitt Romney's presidential aspirations by recording anti-gay marriage robocalls for the National Organization for Marriage (NOM).

In an interview with BuzzFeed, Rubio said he believes the issue is best handled at the state level.

“I've always been uncomfortable with a federal constitutional amendment on anything, in particular on that, because I think it steps on the rights of states to define marriage,” Rubio said.

“That's a two-way street, though,” he added. “If states define marriage as between one man and one woman … if you're going to say it belongs to the states, then you have to respect whatever decision they make. And that includes states like Florida that have passed a constitutional amendment that says marriage is between a man and a woman. And likewise you have states that are headed in a different direction.”

Still, Rubio would not say whether he opposes the Defense of Marriage Act (DOMA), the 1996 law which prevents the federal government from recognizing the legal marriages of gay and lesbian couples.

He called the legal challenge to DOMA “a very interesting constitutional question” on “whether the federal government needs to recognize a state's definition.” (The video is embedded on this page. Visit our video library for more videos.)
