GOP presidential hopeful Herman Cain told CBS News' Hotsheet on Wednesday that he believes being gay is a sin and a choice.

Cain briefly talked about gay rights during a nearly 20-minute long interview.

“I believe homosexuality is a sin because I'm a Bible-believing Christian,” he said. “I believe it's a sin.”

“But I know that some people make that choice. That's their choice,” he added.

“So you believe it's a choice?” the interviewer asked.

“I believe it is a choice,” Cain responded.

Cain's remarks come two days after the former CEO of Godfather's Pizza said he would hire an openly gay staffer to work in his administration as Bob Vander Plaats, the president of the anti-gay marriage group The Family Leader, stood by his side.

The 65-year-old business man was asked in Iowa if he'd be opposed to hiring a qualified openly gay staffer for a White House post.

“Nope, not at all,” he answered. “I wouldn't have a problem with that at all.”

“I just want people who – I want qualified. I want them to basically believe in the Constitution of the United States, so, yep, I don't have a problem with appointing an openly gay person. Because they're not going to try to put sharia law in our laws,” he added. (The video is embedded in the right panel of this page.)

Cain has previously said he would be uncomfortable appointing a Muslim to his administration if elected president.
