Democratic nominee Hillary Clinton went after Infowars radio host Alex Jones in a Thursday speech saying she wondered how dark his heart must be.

Clinton was attacking Trump for pushing fringe theories at the Nevada speech. “It’s also what happens when you listen to the radio host Alex Jones. Who claims that 9/11 and the Oklahoma City bombing are inside jobs. He even said – and this is really just is so disgusting – he even said the victims of the Sandy Hook massacre were child actors and no one was actually killed there,” she said.

Hillary added, “I don’t know what happens in somebody’s mind or how dark their heart must be to say things like that. But Trump doesn’t challenge these lies. He actually went on Jones’ show and said, ‘your reputation is amazing I will not let you down.”

Jones has come out strongly against Clinton and has been pushing theories that she has a grave illness.
