WATCH: Christian author flops after CNN’s Chris Cuomo asks him to prove Trump goes to church

Trump-backing evangelical David Brody went on CNN Wednesday to defend his new book that describes President Donald Trump's "spiritual journey" -- but he had trouble saying whether he thinks the president regularly attends church.

While talking about Trump's newfound faith in God, Brody was asked by CNN's Chris Cuomo whether the president attends church on a regular basis. The question seemed to catch Brody off guard, as he stammered before answering.

"Well he does... he goes to church," Brody said. "But let me tell you this..."

"We certainly don't have the Sunday church cams that we used to have," Cuomo interjected.

"Please understand that he can come on himself and defend his church attendance," Brody said.

Earlier in the segment, Cuomo expressed bafflement that evangelicals could possibly give their full endorsement to Trump.

"The question is, how much of it is really a measure of this man, or are you just giving him a really low bar?" Cuomo asked. "It seems the evangelical community prizes beliefs and behaviors that this president does not and has never exhibited. How do you overcome what he says about people, what he expresses in terms of a lack of compassion for people? A man who says he's never had to ask God for forgiveness?"

Brody insisted that Trump did say that he asks for forgiveness from God -- despite having said in the past that he never did because he has nothing to feel sorry about -- in one interview conducted with Brody.

"You can Google it," Brody helpfully suggested, referring to a private conversation with the president he reported from a golf course.

Brody also suggested that having Trump becoming a "cultural warrior" on behalf of evangelicals was evidence of God having a "sense of humor."
