Donald Trump questioned Hillary Clinton’s faith on Tuesday, claiming there’s “nothing out there” about the former secretary of state’s religious beliefs, according to a video captured by a conservative minister.

The video, taken by E.W. Jackson, a minister and former Republican nominee for lieutenant governor in Virginia, appeared to show part of Trump’s private meeting with evangelical leaders in New York City. Trump went on the attack during the conversation, saying there’s no information out there about Clinton’s faith.

“Now, she’s been in the public eye for years and years, and yet there’s no — there’s nothing out there,” Trump says in the video. “There’s like nothing out there.”

Clinton has brought up several times on the campaign trail that she is a Methodist. But Trump seemed to imply during that whatever Clinton believes would be influenced by President Barack Obama’s faith. Trump, a notorious leader of the “birther” movement who pressured Obama to release his birth certificate in the run-up to the 2012 election, long implied that the President was secretly a Muslim.

“It’s going to be an extension of Obama but it’s going to be worse, because with Obama you had your guard up,” he says in the video. “With Hillary you don’t, and it’s going to be worse.”

Trump went on to say that while he prays for “everyone,” he doesn’t think voters should pray for all leaders. Rather, he said, people should pray for voters to pick “one specific person.”

“We can’t be, again, politically correct, and say ‘we pray for all of our leaders’ because all of your leaders are selling Christianity down the tubes, selling the evangelicals down the tubes,” he says in the video.
