Eric Trump, in the front row of his dad's hush-money trial, bashed Michael Cohen on X while he was on the witness stand

• Eric Trump live-tweeted from his dad's Manhattan hush-money trial on Monday.

• Donald Trump's son bashed Michael Cohen on X as he was on the witness stand in the historic trial.

• "I have never seen anything more rehearsed!" Eric Trump posted.

Eric Trump on Monday took the opportunity to live-tweet from the Manhattan courtroom where his father, Donald Trump, is standing trial on criminal charges related to a hush-money payment made to a porn star.

As Michael Cohen, the former president's personal-attorney-turned-nemesis, was testifying as the prosecution's star witness in the case, Eric Trump slammed his dad's ex-"fixer" in a post on the social media site X.

"I have never seen anything more rehearsed!" Eric Trump, who was seated in the courtroom's front row during the historic trial, posted in reference to Cohen's testimony.

Eric Trump sat directly behind his father with Alina Habba, a lawyer for Donald Trump, to his right and a pair of Secret Service agents to his left.

Cellphones are banned for most people in the courtroom, including journalists (credentialed press are permitted to use their laptops). However, there is an exception for lawyers and those in attendance in the first row, court officers told Business Insider.

Prosecutors called Cohen to the witness stand Monday. He began his testimony by describing an allegedly conspiratorial hey-day before Cohen and Trump's relationship went sour.

One of Cohen's roles included shaping the perception of Trump in the press and trying to keep negative stories out of the papers. Cohen testified that he sometimes lied for Trump and and bullied people to please him.

"The only thing that was on my mind was to accomplish a task to make him happy," Cohen told jurors.

The Manhattan district attorney's office has charged Trump with 34 felony counts for falsifying business records.

Prosecutors allege Trump illegally disguised records reimbursing Cohen for a $130,000 hush-money payment made to adult film actor Stormy Daniels in the days before the 2016 election.

The payment, according to prosecutors, was to buy Daniels' silence over a one-time sexual encounter the porn star says she had with Trump at a Lake Tahoe hotel suite in 2006 during a celebrity golf tournament.

Prosecutors are hoping Cohen's testimony will bolster their argument that Trump orchestrated the payment to Daniels as part of an illegal conspiracy to influence the 2016 election.
