Conservative commentator Glenn Beck has declared Ben Carson's presidential career over after he stated that prison sex proves that being gay is a choice.

During an appearance on CNN's New Day, Carson, a possible GOP presidential candidate, said that prison can make people gay.

“Absolutely,” Carson answered when asked if being gay is a choice. “Because a lot of people go into prison straight and when they come out they're gay.”

Later in the day, Carson apologized for the remark and vowed he would no longer talk about gay rights.

“Goodbye to his presidential career,” Beck told his radio listeners on Friday. “It's over. It's over. There is no way to recover from that. That just sounds like a lunatic. … That is a ridiculous statement on a million fronts. A ridiculous statement.”

“It's not just that he didn't see [the question] coming,” Beck added. “It's that he just thought that was a good answer. That was good enough for him. Just [imagine] I'm at a cocktail party and I'm talking to a friend and they say 'well yeah, you know, you go to prison and you're straight, you get out and you're gay,' don't you look at your friend – I don't care if he's the guy who works at the 7-Eleven and he's not running for president ever – don't you go, 'That's the dumbest thing I've ever heard'?”
