On CBS's "Face the Nation," Trump told host John Dickerson that was he said was he didn’t know what a Seventh-day Adventist was.

“I'm not that familiar with it," he said. “I've heard about it, but I'm not that familiar with it. That wasn't meant to be an insult, obviously, it's just that I don't know about it.”

“Well, it's a harsh way of putting it, but perhaps I could say it that way, yes, because I just don't know about, as I said, I don't know about that.”
