In video released by a Danish film-maker who provided footage to the January 6 committee, Roger Stone, furious he will not be pardoned for his activities around the Capitol attack, is seen to call Ivanka Trump an “abortionist bitch”.

The Republican operative also says Jared Kushner, Ivanka Trump’s husband and like her an adviser to Donald Trump in the White House, “has an IQ of 70”.

The video was shot by Christoffer Guldbrandsen, whose footage of Stone was shown in Thursday’s dramatic January 6 hearing. Then, Stone was shown saying: “I say fuck the voting, let’s get right to the violence.”

The clip in which Stone rants about Ivanka and Kushner was selected but not shown by the committee. First reported by the Daily Beast, the clip shows Stone on the phone in the back of a car on a highway, visibly shaking with anger.

“Jared Kushner has an IQ of 70,” he says. “He’s coming to Miami. We will eject him from Miami very quickly; he will be leaving very quickly. Very quickly.”

Like Donald Trump, Kushner and Ivanka Trump moved to Florida after their time in Washington, rather than move back to New York.

Stone continued: “He has 100 security guards. I will have 5,000 security guards. You want to fight. Let’s fight. Fuck you.”

Stone added: “Fuck you and your abortionist bitch daughter.”

Gulbrandsen, the Beast said, said there was “no doubt” who Stone was talking about.

Stone is a strategist, author and self-confessed dirty trickster. He has long been associated with Donald Trump, through the businessman’s many flirtations with politics and since his election win in 2016.

In 2019, Stone was indicted during the investigation of Russian election interference and links between Trump and Moscow.

Stone was convicted on seven counts of lying to Congress, obstruction of justice and witness tampering. The charges related to his links to Trump’s campaign and to WikiLeaks, which released Democratic party emails obtained by Russian hackers on the same day Trump was shown to have bragged about assaulting women.

Stone was sentenced to 40 months in prison. In December 2020, Trump granted him clemency.

Gulbrandsen told the Beast the clip of Stone ranting on his phone was from 20 January 2021, the day of Joe Biden’s inauguration.

Stone’s activities around the Capitol attack and links to the Oath Keepers and the Proud Boys, far-right groups involved in the riot, have been scrutinised by the January 6 committee. Stone appeared in front of investigators but invoked his fifth-amendment right against self-incrimination.

Gulbrandsen told the Beast: “Roger Stone has been holding out for a pardon till the very last minute. He had first written up a memo … with a plan about encouraging Trump to pardon the lawmakers who had voted against certifying [Biden’s win], and Roger Stone, and some of his clients.”

The film-maker said Stone reduced his wishlist to pardons for himself and Bernie Kerik, a close associate, but was “very upset” when no pardon came.

Gulbrandsen said: “Aside from Donald Trump [Stone] also held Jared Kushner responsible as being the guy who was the point man on the pardon.”

The Beast has also reported that Gulbrandsen recorded Matt Gaetz, the Republican congressman from Florida, telling Stone “the boss still has a very favorable view of you”.

Stone said: “I’ll go down hard, though. I’ll fight it right to the bitter end.”

Gaetz said: “Yeah, but I don’t think you’re going to go down at all at the end of the day.”

Guldbrandsen’s documentary, A Storm Foretold, has been extensively trailed and examined – but not yet released.
