– Donald Trump is doubling down in his criticism of former Miss Universe Alicia Machado, calling her "disgusting," accusing her of making a sex tape, and saying that Hillary Clinton made a big mistake in referencing her during Monday's debate. As for the sex tape, myth-busting site Snopes looked into it, along with rumors that she was an adult-film actress, and finds the allegations to be "mostly untrue." The sex-tape story stems from 2005, when Machado reportedly was filmed having sex with another member of a Spanish reality-TV show. But the grainy night-vision footage of a "covered" couple in bed is not explicit and, given that it stems from a reality show, may have been a staged stunt anyway, says Snopes. In a series of tweets Friday morning, Trump unleashed the following: First: "Wow, Crooked Hillary was duped and used by my worst Miss U. Hillary floated her as an 'angel' without checking her past, which is terrible!" Second: "Using Alicia M in the debate as a paragon of virtue just shows that Crooked Hillary suffers from BAD JUDGEMENT! Hillary was set up by a con." Third: "Did Crooked Hillary help disgusting (check out sex tape and past) Alicia M become a U.S. citizen so she could use her in the debate?" Also surfacing are reports that Machado was implicated in a murder as a getaway driver about 20 years ago and that she threatened a judge, but she wasn't charged over either, reports CBS News. Asked about the allegations on CNN, she said, "I'm no saint girl."
