"We did receive another note" from the jury this morning, Judge Merchan said.

According to Merchan, the jury wants the readback to begin with a description of how the jury should consider that evidence, and what should be drawn from the testimony.

Second, the jury said they want headphones "for use with the evidence laptop."

Merchan says the jury will get both headphones and a speaker so they can listen to the evidence.

Judge Juan Merchan took his seat on the bench and began the day's proceedings.

After introductions from the lawyers, Merchan said his usual, "Good morning, Mr. Trump."

Before Merchan entered the courtroom, one of the court officers left a document on the bench and handed copies to both parties.

Former President Trump has entered the courthouse for the day's proceedings.

The prosecution team has arrived in the courtroom. Prosecutor Josh Steinglass was seen reviewing documents with a court reporter.

Ahead of the start of deliberations this morning, court stenographers are sorting through seven enormous transcript binders that are scattered around the jury box.

With the jury requesting readbacks of testimony, the transcripts are set to play a key role in this morning's proceedings.

About 60 members of the press are packed into the gallery ahead of the proceedings.

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.
