A bombshell tape of porn star Stormy Daniels getting interrogated about her sexual relationship with Donald Trump has been bought by her lawyer.
The footage shows Daniels undergoing a lie-detector test in which she is grilled on gruesome details of the alleged Trump tryst — and she passes with flying colours.
The X-rated actor took the test in 2011 at the request of Bauer Publishing as part of an InStyle magazine expose on the year-long affair but legal threats from Trump's lawyer, Michael Cohen, resulted in the article getting spiked.
The polygraph test report sensationally concludes that Daniels was "truthful about having unprotected vaginal intercourse with Donald Trump in July 2006" and that the "probability of deception was measured to be less than 1 per cent".
The report and a video of the test are in the possession of Daniel's lawyer Michael Avenatti, who told CNN he bought the package for US$25,000 (NZ$35,000).
"We did so to ensure that it would be maintained and kept safely during the litigation and not be destroyed," Avenatti said in a statement.
"We did so after learning that various parties, including mainstream media organization (sic) were attempting to acquire the video and the file and either destroy it or use it for nefarious means."
In the video, which has been viewed by a handful of news outlets, including CNN, polygraph examiner Ronald Slay asks Daniels the following questions:
"Around July 2006, did you have vaginal intercourse with Donald Trump?","Around July 2006, did you have unprotected sex with Donald Trump?" and "Did Trump say you would get on The Apprentice?"
Daniels replied yes to all three. Slay analysed the first two to be truthful while the result for the third question was "inconclusive".
Technically I didn't sleep with the POTUS 12 years ago. There was no sleeping (hehe) and he was just a goofy reality TV star. But I digress...People DO care that he lied about it, had me bullied, broke laws to cover it up, etc. And PS...I am NOT going anywhere. xoxoxo https://t.co/Js9sEnanIk
Slay testified in a sworn declaration dated March 19, 2018 that the results of the exam are "true and correct".
Avenatti, who also provided a copy of the report to the New York Daily News, said it and the tape proved his client, whose real name is Stephanie Clifford, had been telling the truth all along.
"Long before Trump announced his candidacy for the presidency, Clifford passed a lie-detector test confirming her relationship with Trump," Avenatti told the paper.
"Where are his test results claiming otherwise? Where are Cohen's test results claiming otherwise? When this is over, the American people will know the truth about the relationship and the cover-up."
Daniels recently filed a civil case asking that her nondisclosure agreement be nulled because, while she and Cohen signed, Trump did not.
She has offered to return the $US130,000 ($AU170,000) that Cohen paid her in exchange for her silence about the affair, which began just a few weeks after Melania Trump gave birth to Trump's youngest son, Barron, according to court records.
Daniels has claimed she met Trump during a golf event in Lake Tahoe in July 2006. They hooked up several more times in New York and California and their affair continued into 2007, she said.
Last week Cohen, the President's longtime lawyer and trusted confidante filed a motion claiming Daniels owes him $US20 million ($AU26 million) for violating their nondisclosure agreement "at least" 20 times.
The fact that a sitting president is pursuing over $20M in bogus 'damages' against a private citizen, who is only trying to tell the public what really happened, is remarkable. Likely unprecedented in our history. We are NOT going away and we will NOT be intimidated. #basta
Cohen has admitted that he paid Daniels off before the 2016 presidential election, but has refused to say why, or whether he was reimbursed by Trump or his campaign.
Trump has yet to personally address his alleged extramarital affair but has added his name to a motion requesting that Daniel's civil case be moved from a state to a federal court.
"Trump intends to pursue his rights to the fullest extent permitted by law," the motion states, according to the New York Daily News.
