Former Trump attorney Michael Cohen called the president “a fraud, a bully, a racist, a predator, a con man” in the newly released foreword to his new book Disloyal about President Donald Trump.

Cohen also referenced “golden showers in a sex club in Vegas,” but did not explicitly accused Trump of taking part.

“From golden showers in a sex club in Vegas, to tax fraud, to deals with corrupt officials from the former Soviet Union, to catch and kill conspiracies to silence Trump’s clandestine lovers, I wasn’t just a witness to the president’s rise—I was an active and eager participant,” Cohen wrote.

He then depicted himself as a witness who knew Trump better than his own family.

“Apart from his wife and children, I knew Trump better than anyone else did,” Cohen wrote. “In some ways, I knew him better than even his family did because I bore witness to the real man, in strip clubs, shady business meetings, and in the unguarded moments when he revealed who he really was: a cheat, a liar, a fraud, a bully, a racist, a predator, a con man.”

Although the book is yet to be released, the foreword contained significantly damning allegations against the president, including that he “had colluded with the Russians, but not in the sophisticated ways imagined by his detractors.”

“Trump had cheated in the election, with Russian connivance, as you will discover in these pages, because doing anything – and I mean anything – to ‘win’ has always been his business model and way of life,” Cohen wrote.

The president’s former fixer then claimed he personally oversaw a real estate deal in Moscow designed to gain the favorability of Russian President Vladimir Putin.

“Trump had also continued to pursue a major real estate deal in Moscow during the campaign. He attempted to insinuate himself into the world of President Vladimir Putin and his coterie of corrupt billionaire oligarchs,” Cohen wrote. “I know because I personally ran that deal and kept Trump and his children closely informed of all updates.”

Cohen is currently serving a three-year prison sentence in home confinement on charges of lying to Congress and campaign finance violations. He also became entangled in Trump’s personal life, when he became the middle man in paying women hush money during the 2016 campaign who allegedly had prior affairs with Trump.

He was briefly sent back to jail for writing Disloyal, but a judge ruled the move was “retaliatory” and sent Cohen back to home confinement.
