Jurors will deliberate until 4:30 p.m. ET today if they don't reach a verdict sooner, Judge Merchan said.

"You cannot leave the building and you need to be able to get here quickly" when a verdict is reached, the judge told the parties after the jury had left the courtroom.

Former President Trump got up from the defense table and spoke with several associates, then exited the courtroom with his entourage.

The staff and lawyers from the Manhattan district attorney's office also left the courtroom.

As the 12 main jurors left the courtroom, most appeared to look away from Trump as they passed his counsel table.

The six alternate jurors remained in the courtroom after the 12 main jurors left to begin deliberations.

"We are not going to excuse you just yet," Judge Merchan told the alternates,

He asked them to stick around through the deliberations. though they won't participate in the deliberations themselves.

"That concludes my instructions on the law. Counsel please approach," Judge Merchan said when he was done instructing the jury.

He held a sidebar with the attorneys, after which the jurors filed out of the courtroom to begin deliberations.

Judge Merchan emphasized that jurors each need to come to an individual decision about the verdict after hearing and understanding the view of the other jurors.

"Each of you must decide the case for yourself, but only after a fair and impartial consideration of the evidence with the other jurors," Merchan said.

"You should discuss the evidence and consult with each other, listen to each other, give the others' views careful consideration," he said. "You should not surrender an honest view of the evidence simply because you want the trial to end, or because you're outvoted."

"Your verdict on each count you consider must ... be unanimous -- that is, each and every juror must agree to it," Merchan said.

Merchan said that the jury foreperson will read the verdict for each of the charged counts. Merchan will then poll the entire jury to confirm their verdict.

Prosecutor Josh Steinglass continued to lean on the testimony of former National Enquirer publisher David Pecker, arguing it offered unequivocal evidence that Trump was in on the catch-and-kill plan involving Playboy model Karen McDougal.

Pecker testified that Trump was furious at Pecker after the Wall Street Journal published a story in November 2016 about AMI's payment to McDougal.

"This is the story that he is simultaneously telling the press he knows nothing about," Steinglass said. "Pecker established unequivocally that Trump was in on the McDougal deal."

Trump was "angry because story came out that threatened his standing with female voters," Steinglass said.

"Of course we will never know if this effort to hoodwink the American voter made the difference in the 2016 election, but that's not something we have to prove," Steinglass said. What matters, Steinglass said, is that the scheme was "cloaked in false business records to hide the conspiracy."

Judge Merchan said the jury would take its next break, then the closing would continue.

"I was watching the jurors," said the judge. "They looked pretty alert to me -- I don't think we're losing anyone."
