The first group of 96 prospective jurors has been sworn in.

Judge Merchan is now delivering remarks that he said will last about 30 minutes, introducing the case and explaining to prospective jurors their responsibility -- if selected -- to be fair and impartial.

Trump has been leaning forward in his seat listening, with his elbows on the desk.

Dozens of New Yorkers are now being escorted into the courtroom as prospective jurors.

Judge Merchan will deliver a summary of the case before attorneys for both parties have an opportunity to evaluate the prospective jurors' fitness to serve.

According to the pool, 96 individuals will make up the first batch to go through the laborious selection process. Merchan said approximately 200 people have been summoned to the courthouse for potential jury duty on the case.

Trump, during a lengthy break as court officials escorted jurors through security magnetometers, could be seen reclining in his chair and conversing with his attorney Todd Blanche.

Judge Merchan has issued Trump's defense team an ultimatum: Turn over their proposed defense exhibits in 24 hours or be barred from using the materials.

"You have 24 hours," Merchan said. "Anything you don't produce within 24 hours will be precluded."

Defense attorney Todd Blanche pushed back on the deadline, arguing against a prosecutor's assertion that defense withheld materials following a February exhibit deadline for "tactical reasons."

"That is completely false," Blanche said. He asked Merchan for a Wednesday deadline instead, given the demands of the trial.

Merchan declined to grant the request, highlighting the recent flurry of defense motions filed over the last few weeks.

"I don't know how you managed to get those motions out," Merchan said. "The way you choose to use your time is your business."

Judge Merchan has set a hearing on prosecutors' request to hold Trump in contempt for allegedly violating the judge's limited gag order.

After initially setting the hearing for Wednesday, April 24, he rescheduled it for Tuesday, April 23 at 9:30 a.m. ET.

The judge gave Trump's attorneys until April 19 to file their written response.

Prosecutor Christopher Conroy also asked that a copy of the order be served on Trump, and papers were then handed to Trump and defense attorney Todd Blanche at the defense table.

Former President Trump's attorney Emil Bove began his cross-examination of former National Enquirer publisher David Pecker by seeking to painting Pecker and Trump's "mutually beneficially" relationship as one that had nothing to do with the election but rather had been underway for years under a "standard operating procedure."

"Seventeen years of providing President Trump with a heads-up about potentially negative publicity?" Bove asked Pecker.

"That's correct," Pecker said.

Bove asked Pecker about the first time he ever provided Trump with information -- which Pecker testified was in the 1990s and related to a negative story about Marla Maples, Trump's ex-wife.

"Fair to say that predated the Trump Tower meeting by a long time?" Bove asked of Pecker and Trump's relationship.

"Yes," Pecker said.

"A lot of interactions?" Bove asked.

"Yes," Pecker responded.

Pecker also testified about buying and suppressing stories for other individuals, such as one for former Rep. Rahm Emanuel for $20,000.

Bove also sought to show that kind of relationship between publishers and politicians was normal, saying there was "nothing wrong about" it.

"You are aware many politicians work with the media to try to promote their image?" Bove asked.

"Yes," Pecker responded.

"That's standard operating procedure?" Bove again asked.

"Yes," Pecker said.

"And sometimes when politicians are doing that, that is to try to win elections?" Bove continued.

"Right," Pecker responded.

"Nothing wrong about that?" Bove asked.

"No," Pecker responded.
