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."

In June of 2016, as the National Enquirer evaluated the merits of Karen McDougal's claim of a year-long affair with Trump, Trump's attorney Michael Cohen instructed Pecker to purchase her story -- and suggested that Trump would compensate the company for the cost, according to Pecker.

Pecker recalled from the stand a conversation he had with Cohen, in which Cohen told him, "You should go ahead and buy this story."

"So I said to him … 'Who's going to pay for it?'' Pecker testified, saying Cohen replied, "'Don't worry, I'm your friend, the boss will take care of it.'"

Pecker said he interpreted that to mean that if the National Enquirer purchased the story, Trump or the Trump Organization would reimburse him.

Picking up on his testimony from Tuesday, Pecker said that when he spoke with Trump about McDougal's story, he recalled that Trump called McDougal "a nice girl" and asked Pecker what he should do about it.

"I think you should buy this story and take it off the market," Pecker said, explaining that he "believed the story was true. I think that it would be embarrassing to himself and also to his campaign."

During her negotiations with the National Enquirer, McDougal represented that "she didn't want to be the next Monica Lewinsky," Pecker said.
