Trump's lifetime of 'debauchery' has put him in 'peril' — and he knows it: biographer

Donald Trump's lifetime of "debauchery" might be finally catching up with him, according to his biographer, and the former president seems to know it.

The quadruple-indicted former president will appear Monday in court to stand trial on criminal charges related to his hush-money payment to adult film star Stormy Daniels, and his biographer Tim O'Brien said in a new column for Bloomberg that the case ties together all the tawdry threads in Trump's personal life.

"A porn star and a former Playboy Playmate are involved," O'Brien wrote. "Several well-known characters from Trump’s business and political orbits are expected to testify, some of them corrupted by their proximity to him. The seediest sector of the tabloid press plays a pivotal role. One of Trump’s alleged affairs occurred just four months after his wife, Melania, gave birth to their son. And the trial will play out in New York, the city that gave rise to the Trump family’s wealth, myths, business and political traction, and debauchery."

The indictment charges Trump with 34 felony counts related to falsified business records to cover up a reimbursement to his attorney Michael Cohen for the payment to ensure Daniels stayed quiet about their sexual relationship, and O'Brien said the case poses substantial threats to his freedom and political future.

"Whatever the weaknesses of the New York case against him, and it’s possibly the least consequential and muscular of the myriad federal and state charges he faces, Trump seems well aware that he’s in peril," O'Brien wrote. "He continuously ramped up efforts to postpone the trial in recent days, and only seemed to grow more unspooled and histrionic each time the court rejected him. Over the weekend Trump leaned into the flimsiest of his arguments for why he’s being prosecuted."

The ex-president has promised to testify in the case, but O'Brien said his attorneys would be foolish to put the "habitual liar and fabulist" on the stand, and his biographer added that his bluster and attempts to derail the case betrayed his fear.

"Trump’s recent and heated efforts to derail the New York trial suggest there may be other incriminating evidence aired in the courtroom that hasn’t become public yet," O'Brien wrote. "He’s given every indication that he’s worried and that he has something to hide. Perhaps not, but that’s what the trial is for. Jurors will ultimately have to decide if the Republican candidate, anxious about his electoral prospects and reeling from disclosure of the Access-Hollywood-grab-them-by-the-genitals tape in 2016, opened his wallet to suppress another scandal and orchestrated a cover-up along the way."
