On the same day Donald Trump was endorsed by an evangelical leader, Jeb Bush said he had his doubts over the billionaire businessman’s Christianity.

“No, I don’t know what he is,” the former governor of Florida said of Trump when asked if he thinks Trump is a Christian, according to a video posted by ABC News. “I just don’t think he has the relationship that he says he has, if you can’t explain it in any way that shows that he’s serious about it. Just accepting the fact that we make mistakes and you seek forgiveness. That’s one of the tenets of the Christian faith, that I think all, everybody can agree on. We’re all sinners.”
