Former adult film star Stormy Daniels passed a polygraph test in which she admitted having unprotected sex with Donald Trump. She added that the pair did not use protection, a decision that was made “kind of in the moment.” On Tuesday, Michael Avenatti, an attorney for Daniels (whose real name is Stephanie Clifford), confirmed to NBC News that he paid $25,000 for the video of his client taking the test on May 19, 2011. Avenatti also tweeted a video screenshot. Daniels alleges that she met Trump during a charity golf tournament event in Lake Tahoe. The White House has denied the affair, according to CNN. While a polygraph cannot provide indisputable evidence that one is lying, it measures changes in breathing, pulse, blood pressure, and skin gland activity — all physiological signs that a person is undergoing a fight-flight-freeze response.
