The Rev. Franklin Graham, who took over his father Billy Graham's ministry, said he has looked at the field of potential candidates for the 2012 Republican presidential nomination and thinks Donald TrumpDonald TrumpPerez and Ellison agree on DNC playing neutral role in primary Ellison: 'Begin investigations' on impeaching Trump Report: House measure forcing release of info on Trump conflicts likely to die in committee MORE might be the one.
"Donald Trump, when I first saw that he was getting in, I thought, 'Well, this has got to be a joke,'" Graham said on ABC's "This Week." "But the more you listen to him, the more you say to yourself, 'You know, maybe the guy's right.'"
Graham was also asked about Trump's trumpeting of the "birther" theory that President Obama was not born in the United States.
Obama "can solve this whole birth certificate issue pretty quickly," Graham said. "I was born in a hospital in Asheville, N.C., and I know that my records are there. You can probably even go and find out what room my mother was in when I was born. I don't know why he can't produce that."
As for the other GOP hopefuls, Graham said he likes former Alaska Gov. Sarah Palin but isn't sure she will jump into the race.
"I don't think she — she likes politics," he said. "I think she likes speaking on the issues. And I agree with many of the issues that she brings up. But ... I don't see her as running for president."
The reverend was lukewarm on former Massachusetts Gov. Mitt Romney.
"I've met Mitt Romney. No question, he is — he's a very capable person. He's proven himself," he said.
