Alex Jones has released what he claims is a secretly recorded conversation between himself and Megyn Kelly - and is threatening to release the full covertly-recorded audio of their controversial interview before it airs on Sunday.

The Infowars founder on Thursday night hit back at Kelly before the interview even airs, claiming the NBC host will misrepresent his views after she spent the week being hammered by all sides for interviewing the Sandy Hook conspiracy theorist.

In a video posted to Jones' Twitter, a recording of an apparent pre-interview phone call between the two is played, with a woman who sounds like Kelly saying: 'All I can do is give you my word and tell you if there's one thing about me, I do what I say I'm gonna do, and I don't double-cross.'

'You know you just became very fascinating to me. I just always thought you were this maybe, one-dimensional guy, like this is your thing…'

'My goal is for your listeners and the left - you know, who will be watching some on NBC - to say, "Wow, that was really interesting."'

'And then the next time I wanna get somebody, they're gonna say, "Look what you did to Alex Jones!" It's not going to be some gotcha hit piece, I promise you that.'

News of Kelly's interview with Jones has caused outrage, with the parents of Sandy Hook children objecting to her giving Jones the publicity. They were backed up by a number of parents, including Chelsea Clinton.

Amid growing anger, Kelly has been fired as the host of a Sandy Hook charity event and JP Morgan Chase has dropped its adverts from NBC until after the interview airs.

Jones now claims that Kelly will edit the piece to make him look crazy, and so he plans to show his own side of the conversation with an unedited version of the interview.

In the video posted to his Twitter he said: 'Tonight at Infowars.com, we're going to have the full behind-the-scenes with Megyn Kelly released.'

'God, she was like, "I want to get steaks with you, I'm obsessed with you, oh my god," you know, wailing around in her seat - it was all c**p.

'And I knew it was all a lie. I said Sandy Hook happened, everything, she wouldn’t even put it in the promo pieces.

Suspicious: Jones (seen in a preview for Sunday's episode) says he suspected Kelly and NBC would misrepresent him in the TV special over his claims Sandy Hook massacre was a hoax

Under fire: Kelly (seen in preview), 46, has been under fire all week for her upcoming interview with Inforwars' Alex Jones, who has called the Sandy Hook shooting a hoax in the past

'IT'S NOT GOING TO BE A HIT PIECE, PROMISE' In his video Thursday, Jones played what appeared to be a series of samples of Kelly's voice, recorded while she was setting up their interview. This is what it says: 'All I can do is give you my word and tell you if there's one thing about me, I do what I say I'm gonna do, and I don't double-cross.' 'You know you just became very fascinating to me. I just always thought you were this maybe, one-dimensional guy, like this is your thing…' 'My goal is for your listeners and the left - you know, who will be watching some on NBC - to say, "Wow, that was really interesting."' 'And then the next time I wanna get somebody, they're gonna say, "Look what you did to Alex Jones!" It's not going to be some gotcha hit piece, I promise you that.' Advertisement

'And so we’re going to release - oh yeah - we're gonna release the pre-interview.

'And then when they put their fraud out on Sunday - which I've asked them not to air because they're misrepresenting who I am and saying I'm as bad as Saddam Hussein of Jeffrey Dahmer, or, god, Charles Manson... It's crazy.

'We've got the whole interviews here, when she was here from 9:30 in the morning till 11 at night, we got it all. And so you're going to hear what I actually said.'

Rob Dew, a news director for Infowars, doubled down on Jones' promise to release the footage, which they say will include the full, unedited interview.

In her own preview, released last weekend, Kelly demands to know how Jones can call Sandy Hook a hoax, given the loss of young lives and parents who are still grieving for their children.

'Oh I know, but they don't get angry about the half-million dead Iraqis from the sanctions...' starts Jones before he is cut off by Kelly and accused of dodging her question.

'The media doesn't cover all the evil wars...' begins Jones, who again is cut-off by Kelly.

'That doesn't excuse the things you said about Newtown, you know that,' states Kelly, who actually traveled to Texas to meet with Jones in his own studio.

Over the last few days, Jones has claimed this is bad editing and not what his actual responses to her questions were.

'It has all the markings of a PR stunt,' he told The Hollywood Reporter. 'They just want me to be the devil because I'm the alternative media... Fake news lives at NBC.

'They basically made me look like a Halloween character.'

ALEX JONES RANTS AT MEGYN In the preview video released Thursday, Jones said: 'I've never done this in 22 years, I've never recorded another journalist, I've never done this but I knew it was a fraud, that it was lie. 'God, she was like, "I want to get steaks with you, I'm obsessed with you, oh my god," you know, wailing around in her seat - it was all c**p. 'And I knew it was all a lie. I said Sandy Hook happened, everything, she wouldn’t even put it in the promo pieces. 'And so we’re going to release - oh yeah - we're gonna release the pre-interview. 'And then when they put their fraud out on Sunday - which I've asked them not to air because they're misrepresenting who I am and saying I'm as bad as Saddam Hussein of Jeffrey Dahmer, or, god, Charles Manson... It's crazy. 'We've got the whole interviews here, when she was here from 9:30 in the morning till 11 at night, we got it all. And so you're going to hear what I actually said. 'Like when it cuts, and they go "Oh, so you don't think that Sandy Hook happened," and I go, "Yeah, we don't care about dead Iraqi kids," I'm like, "Hey, they did fake babies in incubators, they did fake dead kids, that's why we have got to question this, I don't hate the families, we question everything. 'It's all going to come out. And tonight, at Infowars.com, we're going to have the full behind-the-scenes With Megyn Kelly released, the full Megyn Kelly, Alex Jones interview ... 'Get ready! Because it's the 21st century, and it's an Infowar!' Advertisement

In truth, Jones has a long history of making startling claims about the shooting, in which 20 children aged 6-7, and six adults, were gunned down at the school in 2012.

In 2013 and 2014, he called the shooting 'staged', an 'inside job' and 'pre-planned'.

And in 2015, he called it 'completely fake, synthetic, with actors - in my view manufactured'.

ALEX JONES' SANDY HOOK REMARKS 2013 Jones called the shooting 'staged' and said: 'It's got inside job written all over it.' 2014 In March of this year, he said: 'I've looked at it and undoubtedly there's a cover-up, there's actors, they're manipulating, they've been caught lying, and they were pre-planning before it and rolled out with it.' 2015 He claimed that 'Sandy Hook is completely fake, synthetic, with actors - in my view, manufactured.' He continued: 'I couldn't believe it at first, I knew they had actors there, clearly, but I thought they killed some real kids, and it just shows how bold they are that they clearly used actors.'

Since then, Jones has revised his comments, saying that children were killed, but that something was unusual about the event.

That has done little to mollify the parents of those involved, however, who have received harassment from the so-called 'Sandy Hook truthers' who have accused them of faking their own kids' deaths.

According to Page Six, Kelly has responded to the criticism by inviting Sandy Hook families onto the program and editing her interview with Jones to be tougher on the conspiracy theorist.

Neil Heslin, the father of six-year-old Jesse Lewis, who was slain in the Sandy Hook massacre in Newtown, Connecticut, has reportedly agreed to be interviewed on Kelly's show.

Kelly herself spoke about the controversy in an interview with The New York Times while defending her decision to bring Jones on her program.

'What we do as journalists is we shine a light on those with power, those with influence, those who have become culturally relevant,' she said.

'Of course, it's upsetting to know that doing that causes any upset to the Newtown families, many of whom I know well. But I have to do my job.'

Kelly (pictured on Wednesday) has been under fire ever since Sunday, when she revealed on her news magazine that she would be interviewing Jones, a known conspiracy theorist

Kelly has been under fire ever since Sunday, when she revealed on her news magazine that she would be interviewing Jones.

On Thursday, however, she finally got a little support from a very unlikely place when CNN president and former NBC boss Jeff Zucker hopped to her defense.

'I think the issue here is they way that they have thus far presented it has not led to the belief that he's held to account as much as somebody who spews such hatred and nonsense needs to be,' said Zucker in an interview with The Hollywood Reporter.

'If you're going to do this story the tease needs to be you holding up a picture of the dead kids at Sandy Hook and saying, "How dare you?" And I think their marketing of this has thus far been unfortunate.'

Zucker, who had been hoping to convince Kelly to join the team at CNN when her contract was up, also noted that the new NBC hire is a 'very good journalist.'

'As journalists, we don't get to interview only the good guys - that's not journalism,' Kelly told the Times.

'It's going to be very difficult for us to keep an eye on the more controversial figures of our time if we never talk to them.'

Kelly said she sat down with Jones to examine 'his influence and his - for lack of a better term - method for putting information together to figure out how he got to be so important in the president's world, in millions of people's world.'

She also stated that currently 'there are a lot of people who are very angry that Donald Trump is president and a lot of people who believe Alex Jones played a large role in it.'

Kelly is also dealing with another problem: The second episode of her NBC news magazine tanked in the ratings, losing almost half its audience from the premiere one week prior.

Final Nielsen numbers show that the latest episode of 'Sunday Night With Megyn Kelly' pulled in 3.61 million total viewers and scored an 0.6 rating in the all-important adults 18-49 demo, which was a slight improvement in the 7pm time slot from the previous year.

It was far, far lower, however, than the 6.1 million viewers and 0.8 rating notched up by the premiere, which featured an interview with Russian president Vladimir Putin.

On Monday, Sandy Hook Promise, an organization that was created in memory of the 20 students and six staff members who were massacred in the 2012 school shooting in Newton, Connecticut, announced that Kelly would no longer host one of their annual Promise Champions Galas.

That announcement came just two days before she was set to take the stage at the event on Wednesday night in Washington DC.

The decision made by the non-profit organization also leaves Kelly with a big gap in her episode that will be airing this Sunday, as she planned to film the gala to run alongside her interview with Jones.

That plan went up in smoke, however, when she managed to draw the ire of Sandy Hook parents, who lashed out loud and quick as they attacked Kelly for allowing Jones' ideas to be heard by her audience of six million.

Kelly responded to the controversy on Tuesday in a statement, saying she was 'disappointed' but also 'respected the decision' of the charity.

'I understand and respect the decision of the event organizers but I'm of course disappointed that I won't be there to support them on Wednesday night,' began Kelly in her statement.

'I find Alex Jones' suggestion that Sandy Hook was "a hoax" as personally revolting as every other rational person does.'

She then explained: 'It left me, and many other Americans, asking the very question that prompted this interview: how does Jones, who traffics in these outrageous conspiracy theories, have the respect of the president of the United States and a growing audience of millions?'

Kelly then offered theories, stating: 'President Trump, by praising and citing him, appearing on his show, and giving him White House press credentials, has helped elevate Jones, to the alarm of many.'

'Our goal in sitting down with him was to shine a light - as journalists are supposed to do - on this influential figure, and yes - to discuss the considerable falsehoods he has promoted with near impunity,' said Kelly.

Regardless of the aim, advertisers were not happy, and JP Morgan pulled their spots from the time slot.
