Stormy Daniels passed a lie detector test about sex with Trump

Adult film actress Stormy Daniels underwent a polygraph exam about her relationship with Donald Trump, and the examiner found there was a more than 99 percent probability she told the truth when she said they had unprotected sex in 2006, according to a copy of the report obtained by NBC News Tuesday.

Daniels, whose legal name is Stephanie Clifford, took the lie detector test at the request of a magazine that interviewed her in 2011, but didn't publish the content at the time.

The report is accompanied by a sworn declaration from the examiner, signed on Monday, March 19, 2018, attesting to the polygraph report's authenticity. Details of the report were first published by The Wall Street Journal on Tuesday.

Michael Avenatti, Clifford's attorney, has confirmed to NBC News that this photo is a from a video of Clifford taken during a polygraph exam conducted in May 2011 at which she was asked about her relationship with Trump.

"Long before Mr. Trump announced his candidacy for the presidency, Ms. Clifford passed a lie detector test confirming her relationship with Mr. Trump," Avenatti said. "Where are his test results claiming otherwise? Where are Mr. Cohen’s test results claiming otherwise? When this is over, the American people will know the truth about the relationship and the cover-up."

Clifford is now locked in a legal battle with Trump and his team over a nondisclosure agreement she signed shortly before the 2016 election in exchange for $130,000.

Trump denies having had a sexual relationship with Clifford. His personal attorney, Michael Cohen, says he "facilitated" the $130,000 payment with his personal funds and was not reimbursed by the Trump Organization or the campaign.

Earlier this month, Clifford sued Trump, saying the secrecy agreement she signed isn’t valid because he never signed it. Trump and Cohen has since moved the suit to federal court and want a judge to push the matter into private arbitration.

Years before the agreement, Daniels gave an interview to InTouch magazine, which has said that she passed a polygraph. Details of that exam, however, have not been released until now.

The report, prepared by a Las Vegas company called Western Security Consultants, says the purpose of the polygraph examination was to "determine if Ms. Clifford had vaginal intercourse with Donald Trump in July 2006."

The examiner asked her a series of questions, three of which were relevant to the alleged affair:

"Around July 2006, did you have vaginal intercourse with Donald Trump?"

"Around July 2006, did you have unprotected sex with Donald Trump?"

"Did Trump say he would get you on 'The Apprentice'?"

Clifford answered "yes" to all three, according to the report.

The examiner used two methods to analyze the data, according to his report. The first, using an algorithm the report said was developed by Johns Hopkins University, found there was a 1 percent chance of deception for the three answers. A second analysis method found there was adequate evidence Clifford was telling the truth on the first two questions, and it was inconclusive for the third, according to the report.

The White House and Cohen did not immediately respond to request for comment about the polygraph results.

The report says the exam was requested by Life & Style, a sister publication of InTouch. Former employees of publisher Bauer told the Associated Press the interview with Clifford did not run in 2011 because Cohen threatened the magazine with legal action.

They did publish it in February, after news of the $130,000 payment to Clifford broke. In it, Clifford described meeting Trump — who was already married to Melania — at a charity event in Lake Tahoe and having sex in his hotel room.

In her lawsuit, she said only that they had an ""intimate" relationship that began in 2006 and continued in 2007. She has taped an interview with "60 Minutes" that is scheduled to air on Sunday.

Cohen and his attorney have warned that they consider Clifford in breach of the 2016 nondisclosure agreement and a temporary restraining order they secretly obtained before her lawsuit was filed.

Court papers filed by the Trump team Friday say she is liable for $1 million in damages each time she violates the terms and is already on the hook for $20 million.

Although the White House has sought to distance the president from the Clifford dispute — press secretary Sarah Sanders said she doesn't think he knew about the $130,000 payment — Trump consented to move the matter from state court to federal court in California.
