NBC anchor Megyn Kelly challenged InfoWars host Alex Jones about his conspiracy theories about the Sandy Hook elementary school massacre during a controversial interview that aired Sunday night.

"In our interview, we asked Jones numerous times what he now believes," Kelly said of his views about the school shooting. "He never completely disavowed his previous statements."

Kelly's interview with Jones on the new Sunday Night with Megyn Kelly show drew controversy in the lead-up to its airing: Jones, known for promoting wild conspiracy theories on his radio show, has suggested the Sandy Hook Elementary massacre was actually a hoax. Twenty children and six adults were killed by in what was one the deadliest mass shootings at a school in the country's history.

"I tend to believe children probably did die there," Jones told Kelly. "You look at the other evidence on the other side. I can see how other people believe nobody died there."

Kelly defended her interview at the beginning of the show, saying Jones "isn't going away" and he has access to President Trump. Kelly said Jones has "spent nearly two decades on the fringe, shouting his conspiracy theories into every microphone he can get in front of."

"First tonight our report on the incendiary radio host Alex Jones," Kelly said. "For years, Jones has been spreading conspiracy theories claiming for instance that elements of the U.S. government allowed the 9/11 attacks to happen and that the horrific Sandy Hook massacre was a hoax."

Kelly peppered Jones with questions about his claims about the massacre. Jones seemed to argue he was playing "devil's advocate" with some of his statements.

At one point, Kelly put both hands on her forehead and said: "Alex, the parents, one after the other, devastated. The dead bodies that the coroner autopsied."

Jones shot back: "And they blocked that. They won't release it. It's unprecedented. Even the reports. "

He also said he "watched the footage" of the "kids going in circles in and out of the building with their hands up."

"It looks like a drill," Jones argued. "I have watched the footage."

Families of Sandy Hook victims called on NBC to pull the interview before it aired as to not give Jones a larger platform. Kelly was also disinvited from hosting a gala for an anti-gun violence organization founded by parents of victims.

Defending her interview, Kelly said: "Some thought we shouldn't broadcast this interview because his baseless allegations aren't just offensive, they're dangerous. But here's the thing: Alex Jones isn't going away. Over the years his YouTube channel has racked up 1.3 billion views. He has millions of listeners and the ear of our current president."
