The dossier also introduced what's commonly called "the pee pee tape" — allegations that Trump hired prostitutes to join him in the presidential suite of a Moscow hotel and urinate on the bed in which President Obama and Michelle Obama slept on a trip to Russia. This was videotaped, the dossier says, and the Kremlin is blackmailing Trump with it.
 
As the Trump-Russia story unfolds, many of the dossier's claims have been corroborated, except the sexually related details. And they may never be, says a former National Security Agency analyst and counterintelligence officer, partly because the Kremlin is circulating fake Trump sex tapes that could discredit any evidence of his legitimate sexual misconduct.
