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.

Turning to Michael Cohen's testimony, the jury reheard his testimony, under questioning from prosecutors, that Pecker -- during the 2015 Trump Tower meeting -- vowed to keep an eye out for "anything negative about Mr. Trump" and flag them to Cohen.

Q: Could you tell the jury, please, what was discussed and what was agreed to at that meeting?

A: What was discussed was the power of the National Enquirer in terms of being located at the cash register of so many supermarkets and bodegas; that if we can place positive stories about Mr. Trump, that would be beneficial; that if we could place negative stories about some of the other candidates, that would also be beneficial.

Q: Was there anything else that Mr. Pecker said he could also do for Mr. Trump's candidacy?

A: Yeah.

Q: What, in substance, did he say?

A: What he said was that he could keep an eye out for anything negative about Mr. Trump, and that he would be able to help us to know in advance what was coming out and try to stop it from coming out.

Q: And who did he say he would get in touch with if his -- he was able to identify those types of stories?

A: The answer was: Me. Mr. Trump also. Knowing my relationship with David, "The two of you should work together. And anything negative that comes , you let Michael know, and we'll handle it."
