President Donald Trump on Sunday said he believed the gunman who attacked the White House Correspondents’ Association dinner hated Christians, suggesting the violence could have been religiously motivated.

“The guy is a sick guy when you read his manifesto. He hates Christians. That’s one thing for sure. He hates Christians, a hatred,” Trump said during an interview on Fox News’s The Sunday Briefing. “He had a lot of hatred in his heart. … It was a religious thing.”
