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."

After a week-long selection process, the jurors in Donald Trump's New York hush money case are scheduled to hear opening statements this morning in the first criminal trial of a former U.S. president.

To prove their case, lawyers for Manhattan District Attorney Alvin Bragg need to convince twelve jurors beyond a reasonable doubt that Trump repeatedly falsified records to unlawfully influence the 2016 presidential election.

"This case has nothing to do with your personal politics or your feelings about a particular political issue," prosecutor Joshua Steinglass told prospective jurors on Thursday. "It's not a referendum on the Trump presidency, a popularity contest, or any indication of who you plan to vote for this fall. This case is about whether this man broke the law."

Trump's lawyers are expected to focus their efforts on going after the credibility of prosecution witnesses, suggesting the case itself is politically motivated and arguing that the former president never intended to commit a crime.
