Sen. Marco Rubio says he believes sexual orientation is something you are born with but does not believe same-sex marriage is a constitutional right.

Rubio spoke on CBS’s Face the Nation about LGBT rights , among other topics, on April 19 saying that he doesn’t believe the courts should be making the decisions on same-sex marriage.

“It’s not that I’m against gay marriage,” said Rubio. “I believe the definition of the institution of marriage should be between one man and one woman. States have always regulated marriage. And if a state wants to have a different definition, you should petition the state legislature and have a political debate.”

“I don’t believe same-sex marriage is a constitutional right. I also don’t believe that your sexual preferences are a choice for the vast and enormous majority of people. In fact — the bottom line is that — you know, I believe that sexual preference is something that people are born with,” he said.

Rubio announced April 13 that he is running to be the Republican nominee for the 2016 presidential race, one day after Hillary Clinton released a video announcing her run to be the Democratic nominee which featured a gay couple talking about getting married.
