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.

Three prospective jurors now remain from the first group of 96, and they're facing questions from Trump attorney Todd Blanche after fielding questions from prosecutor Susan Hoffinger regarding their jury questionnaire.

The three are a civil litigator, a real estate developer, and a retired New York Police Department photographer.

Asked what he thought about Trump's book "The Art of the Deal," which he previously stated that he had read, the real estate developer said, "I felt it was entertaining." He added that, as a developer, he was "an admirer from afar of some of the work" Trump has done, but he has no opinion on "how he conducts himself."

The civil litigator claimed to know "virtually nothing" about criminal law.

Trump, watching from the defense table, leaned back in his chair slightly and alternated looking ahead and in the direction of the prospective jurors as they read aloud their answers from the questionnaire.
