Day 6 of Donald Trump's criminal trial will begin with a hearing in front of Judge Juan Merchan in which prosecutors will seek to have the former president held in contempt for repeatedly violating the limited gag order in the case.

Prosecutors have argued that Trump violated the limited gag order -- which prohibits statements about witnesses, jurors, and lawyers in the case other than Manhattan District Attorney Alvin Bragg -- on at least ten separate occasions this month, and have asked the judge to hold him in contempt of court and fine him $10,000.

Trump's lawyers have argued that prosecutors have not proven the posts in question were willful violations of the gag order, telling Merchan that the former president was defending himself from attacks by the likely witnesses.

Following the hearing, testimony in the hush money trial is scheduled to resume with former National Enquirer publisher David Pecker on the stand. Prosecutors believe he is key to understanding Trump’s motivation for paying off Stormy Daniels so damaging information did not seep into the 2016 campaign.

Moments after his criminal trial adjourned for the day, Donald Trump exited the courtroom and told reporters that his payments to his former attorney Michael Cohen were appropriately labeled as legal expenses.

"Actually, nobody's been able to say what you're supposed to call it," Trump told the media. "If the lawyer puts in a bill or an invoice and you pay the bill ... that's a very small little line ... it's not like you could tell a life story."

"They marked it down for a legal expense. This is what I got indicted over," Trump said.

The former president also attempted to paint Cohen as an unreliable witness and said he "wasn't very good in a lot of ways" as an attorney.

David Pecker stepped off the witness stand after his initial testimony. He is scheduled to return to the witness stand tomorrow at 11 a.m. ET.

During his brief testimony, Pecker suggested that former National Enquirer Chief Content Officer Dylan Howard -- an alleged participant in the catch-and-kill scheme alleged by prosecutors -- will be unable to testify due to a medical condition.

Pecker appeared to greet Trump and his lawyers as he exited the courtroom.

Court subsequently wrapped for the day.

Trump left the courtroom flanked by Secret Service agents and staffers, as well as Trump Organization General Counsel Alan Garten.

Judge Merchan is scheduled to hold a contempt hearing about Trump’s alleged violations of the case’s limited gag order tomorrow morning at 9:30 a.m. ET.

David Pecker, who once called Donald Trump "a personal friend of mine," flashed a big smile as he took the stand as the trial's first witness, belying the gravity of the moment.

Pecker cackled loudly into the microphone, jolting the room, when prosecutor Josh Steinglass, asked him about his various phone numbers that he struggled to remember.

Pecker, 72, was the publisher of the National Enquirer but prosecutors said he was "acting as a co-conspirator" in helping buy and bury damaging stories about Trump, including a doorman's false claim that Trump had fathered a love child and a Playboy model's claim of a sexual relationship with Trump, who has denied both allegations.

Trump, who once said Pecker would make a "brilliant" choice as editor of Time magazine, listened while leaning forward in his chair, arms crossed on the table, an unhappy look on his face.

Pecker testified that he had final say whether to publish any story involving a famous person.

"I had the final say of the celebrity side of the magazine," Pecker said. "We used checkbook journalism. We paid for stories."

Pecker is testifying pursuant to a subpoena. He has also secured a non-prosecution agreement with the Manhattan district attorney's office.

If former President Trump opts to testify in the trial, prosecutors want to question him about all the times he has been held liable in civil court, according to a new court filing in the case.

Prosecutors have asked Judge Juan Merchan to hold a hearing, known as a Sandoval hearing, to determine the scope of what they can ask Trump on cross-examination.

"We are prepared to do a Sandoval hearing now, later or whenever the court desires," Assistant District Attorney Joshua Steinglass said on Monday.

The judge has not set a date for the hearing but suggested it could be Friday.

In their filing, prosecutors outlined the civil cases they'd like to bring up during the criminal trial, including the $464 million judgment in Trump's civil fraud case, the defamation and battery cases brought by E. Jean Carroll and a lawsuit Trump filed against Hillary Clinton claiming she conspired to rig the 2016 election, for which Trump and his lawyers faced legal sanctions after the case was thrown out as frivolous.

Prosecutors also want to question Trump about a criminal case his company lost in 2022, when the Trump Organization was convicted of tax evasion by providing non-cash compensation to top executives.

They also want to bring up a civil case the New York attorney general won against the Trump Foundation for misusing charitable donations.
