Real estate mogul Donald Trump says he doesn't feel good about gay marriage.

On the Wednesday edition of Fox News' The O'Reilly Factor, the billionaire entrepreneur reiterated his opposition to allowing gay and lesbian couples to marry.

“I'm against it,” Trump told his host. “I just don't feel good about it, I don't feel right about it. I'm against it.”

“And I take a lot of heat because I come from New York. You know for New York it's like, 'How can you be against gay marriage?' But I'm opposed to gay marriage.”

When O'Reilly pointed out that supporters argue that denying access to marriage violates the civil rights of gay couples, Trump responded: “I say that we have other problems in this country.”

“And I don't think a president should be elected on gay marriage or not gay marriage, because we have some very big problems,” he added.

Trump, who has said he'll announce in June whether he'll run for president as a Republican, earlier told the Des Moines Register that he opposes all forms of legal recognition for gay couples, not just marriage.

“They should not be able to marry,” he said.

“Trump said on marriage and civil benefits, 'As of this moment, I would say no and no,'” the paper reported.
