Judge Merchan, returning to the bench, announced, "We did just receive another note."

The judge said the jury wants to rehear the judge's instructions.

Merchan suggested bringing them back to clarify if they want the entire instructions or just a portion.

In his closing argument yesterday, prosecutor Josh Steinglass framed the 2015 Trump Tower meeting, for which the jury requested the transcript, as central to the case.

"That was the whole purpose of the Trump Tower meeting, to get AMI to help [Trump] win the election," Steinglass told the jurors, claiming that "the Trump Tower conspiracy violated New York state election law."

Defense attorney Todd Blanche, in his closing, pushed back on the significance of the meeting, saying it was AMI merely agreeing to do what it had done for decades.

"They had been doing it for President Trump since the Nineties," Blanche said of the arrangement to catch and kill unflattering stories. "Mr. Pecker told you that AMI purchases stories all the time.

"They purchased stories about Tiger Woods, Mark Wahlberg and other people. No crime," Blanche said.

The phone call between Trump and then-National Enquirer publisher David Pecker, which the jury requested be read back, involved an alleged discussion about Playboy model Karen McDougal, who alleged a year-long affair with Trump that Trump has denied.

"With all of the evidence and documents in this case, it's easy to lose sight of the significance of this phone call," prosecutor Josh Steinglass told jurors during his closing argument yesterday.

Steinglass argued that the call proved that Trump "was overtly discussing purchasing [McDougal's] story to keep it from being published" -- and that it also proved that Michael Cohen was telling the truth when he said he was acting at the direction of Trump.

"This call makes it impossible for the defense to claim that Cohen was acting on his own, that he was taking it upon himself to work with AMI to purchase the McDougal story," Steinglass told the jurors.

"I will be in the robing room -- let me know when you are ready for readback," Judge Merchan said after the jury requested a review of four pieces of testimony from Michael Cohen and David Pecker.

Merchan then left the courtroom.

A court reporter dropped a 12-inch stack of transcripts on the prosecution counsel table then handed an index to the prosecutors.

Trump attorneys Emil Bove and and Todd Blanche appeared to be searching through papers on their table, while Trump sat motionless. Prosecutors were doing the same thing.

As ABC News reported previously, the U.S. Secret Service spent considerable time working with New York City court and jail officials to determine what would happen if the judge, as threatened during trial, ordered former President Trump to be incarcerated for contempt -- a situation that did not come to pass.

According to an official briefed on the matter, U.S. Secret Service planners have not started the process of determining arrangements for Trump to be imprisoned at a New York state penitentiary in the event he is convicted. Because Trump is charged with nonviolent crimes, has no criminal record, and was allowed to remain free before trial, it is believed that there is no way that a conviction would lead to immediate incarceration.

If Trump is convicted, the Secret Service will spend the time prior to sentencing -- which could be months -- working with New York state prison officials to determine how imprisonment would work. An official told ABC News that potential questions could include, would USSS agents be armed inside prisons where firearms are prohibited? What prison would Trump be assigned to? Where would protection agents be stationed in relation to Trump? Those details, among many others, would have to be hammered out, the official said.

The Secret Service specifically avoided planning on a possible prison sentence during the trial so Trump and his loyalists could not accuse them of taking sides against the former president, the official said.
