Franklin Graham, the son of Rev. Billy Graham, produced a serious of eye-brow raising comments on MSNBC's Morning Joe Tuesday, including having uncertainty on President Barack Obama's faith.

Co-host Willie Geist began the discussion with Graham by asking if he agreed with Rick Santorum on whether Obama was a Christian.

"I think you have to ask President Obama," Graham said. "You can ask me if I believe you are a Christian, I think the best thing is to ask a person directly, so I think people have to ask Barack Obama. He's come out saying he's a Christian, so the question is, 'What is a Christian?'"

"So you don't take him at his word what is a Christian?" Geist asked.

"No, of course I do," Graham replied. "You have to ask every person that he has said he is a Christian, so I just have to assume that he is."

“So therefore, by your definition, he’s not a Christian?” Geist pressed.

“You have to ask him,” Graham said. “I cannot answer that question for anybody.”

Co-host Mike Barnacle expressed frustration with the likes of Graham over their continued uncertainly on the issue, asking him, "Why can't you just say he's Christian?"

Geist later asked Graham if he believed Rick Santorum was a Christian. After Graham thought the former Pennsylvania Senator was, Geist and guest panelist John Heilemann highlighted Graham's hypocrisy.

"That is an amazing double standard that you just applied," Heilemann said. "Your reaction to the difference of the question about Rick Sanorum and President Obama just exposes the incredible double standard you're applying to those two people. They're exactly the same situation."

Graham also was not willing to consider Mitt Romney and Mormons as Christians during the interview.

"Most Christians would not recognize Mormonism as part of the Christian faith," he said. "Of course they believe in Jesus Christ, but that have a lot of other things they believe in too that we don't accept theologically."
