The Manhattan district attorney's office has filed its formal request to hold former President Trump in contempt over a series of recent social media posts that, among other things, call witnesses Michael Cohen and Stormy Daniels "sleaze bags."

Prosecutors said yesterday that three of Trump's social media posts this month "plainly violate" Judge Merchan's limited gag order because they target known witnesses who will testify at the trial.

"And defendant's violations were knowing and willful -- indeed, they are the latest in what this Court has already recognized as a deliberate strategy to impede this criminal trial," prosecutors wrote in Tuesday's filing. "To be sure, defendant has loudly and repeatedly complained that the order is unlawful, in both court filings and other public statements. But no court has agreed with his objections, and a defendant's mere disagreement with a court's order is no defense to criminal contempt."

Defense attorneys have insisted Trump was responding to "repeated, salacious, demon attacks" by Daniels and Cohen.

The judge has scheduled a hearing on the matter next Tuesday.

Former President Trump has reclaimed his seat at the defendant's table, Judge Juan Merchan is back on the bench -- and the second day of the criminal trial of the former president is underway.

Trump greeted court officers upon arrival, mouthing to one, "How are you?" as he made his way down the aisle accompanied by lawyers Todd Blanche, Susan Necheles and Emil Bove.

Trump is once again seated between Blanche and Bove.

The three men appeared to be in and out of conversation as they awaited the judge, with Trump periodically looking down at the desk or at the monitor in front of him.

Former President Trump, addressing reporters on his way into court, defended the way payments were made to his former attorney Michael Cohen, pushing back on the crux of the DA's case that they were improperly labeled as legal expenses.

"I was paying a lawyer and I marked it down as a legal expense, some accountant," Trump said. "I didn't know. That's exactly what it was."

Manhattan District Attorney Alvin Bragg has accused Trump of improperly labeling the money as legal expenses to Cohen in order to hide that the funds were to repay hush money paid to Stormy Daniels to boost Trump's electoral prospects.

"Legal expense -- that's what you're supposed to call it," Trump said.

"This is a trial that should never happen, it should have been thrown out," he said.

Former President Trump has arrived at the courthouse for the second day of jury selection.

Unlike Monday when a small group of supporters and protesters greeted the former president, there were essentially none at the courthouse this morning.

He again railed on social media against the limited gag order that prevents him from targeting witnesses and others associated with the case.

"I want to speak, or at least be able to respond," Trump wrote on his social media platform, attacking Judge Juan Merchan and again claiming the trial is "election interference."

Former National Enquirer publisher David Pecker testified on cross-examination that the publication's limited involvement in Stormy Daniels' hush money payment was unrelated to the August 2015 Trump Tower meeting where Pecker vowed to serve as the "eyes and ears" of Trump's presidential campaign.

Pecker's testimony on cross-examination about the Daniels story appeared consistent with his testimony yesterday about his strong desire not to be involved in the Stormy Daniels payment.

Pecker said yesterday that he did not want to be involved in the story due to concerns about reputational harm to the National Enquirer and a lack of reimbursement for the other payments he had made to suppress previous Trump stories.

"I said, we already paid $30,000 to the doorman, we paid $150,000 to Karen McDougal, and I am not a bank. I am not paying out any further disbursements among us," Pecker testified yesterday. Pecker said he instructed National Enquirer Chief Content Officer Dylan Howard to flag the Stormy Daniels story to Michael Cohen, who made the payment to Daniels himself.

Asked about Daniels' payment on cross-examination, Pecker said that the National Enquirer's limited involvement was unrelated to their vow to Trump.

"You did not consider the Stormy Daniels story to be part of any agreement you had in August 2015?" defense attorney Emil Bove asked.

"That is correct," Pecker said.

"You wanted nothing to do with it?" Bove said.

"That's correct," Pecker said.

Pecker added that he did not "authorize" Howard to continue communicating with Stormy Daniels' lawyer Keith Davidson about the payment.

When Howard raised concerns to Pecker that Davidson had not yet been paid by Michael Cohen, Pecker said he was angry that Howard continued to communicate with Davidson about the story. In addition to the nature of the story -- which Pecker said could endanger the National Enquirer's relationship with its distributors -- Pecker said Cohen's delay in paying Daniels' lawyer could result in reputational harm to the National Enquirer.

"Frankly, you were not happy to be hearing that?" Bove asked about Cohen's delayed payment.

"Yes," Pecker said.

"The main concern was Howard's reputation?" Bove asked.

"Yes," Pecker said.
