Judge Merchan told the jury that they should not speculate about the sentence or punishment in the case.

"It will be my responsibility to impose an appropriate sentence," Merchan said.

The judge also had to advise the jury about this yesterday after defense lawyer Todd Blanche argued that the jury "cannot send somebody to prison" based on Michael Cohen's testimony.

The jury appears to be laser focused on Merchan during the charge. Half of the jurors appear to be taking notes.

"It is not my responsibility to judge the evidence here. It is yours," Judge Merchan told the jurors as he began his instructions for their deliberations.

"You are the judges of the facts, and you are responsible for deciding whether the defendant is guilty or not guilty."

The judge instructed jurors on avoiding "stereotypes" or "implicit biases" in their deliberations.

"As a juror you are asked to make a very important decision about another member of the community," he said.

Judge Juan Merchan took his seat on the bench, and Trump flashed a closed mouth smile when the judge said good morning in his usual fashion.

Before bringing the jury back into the courtroom, Merchan asked the parties to confirm the proposed verdict form.

Prosecutor Josh Steinglass flagged a minor typo, but both sides appeared to be in agreement about the form, which will the jury will fill out once they render a verdict.

After the jury was brought into the courtroom, Merchan told them the reading of the jury charge will take approximately an hour.

Former President Trump did not speak with reporters as he entered the courtroom this morning, but instead made a series of posts on social media.

Referring to prosecutors' five-hour closing statement yesterday, Trump wrote, "THE D.A.’s OFFICE WAS ALLOWED TO GO ON WITH 5 HOURS OF BULL---- YESTERDAY."

The defense's closing argument took three hours.

As jurors begin their second day of deliberations, Trump's legal team feels that the longer the jury deliberates, the more they're hoping for a hung jury, sources told ABC News.

Trump's lawyers see the requests the jury has made to rehear testimony from the case as a mixed bag, the sources said -- not positive news that jurors wanted to rehear former National Enquirer publisher David Pecker's testimony, but at the same time feeling optimistic that jurors requested portions of Michael Cohen's transcript.

Trump's attorneys are looking for any indication that the jury will probe issues surrounding Cohen's credibility, which cuts to the core of their defense, according to the sources.

"We want chaos ... we want evidence of strong disagreements," one person close to Trump's legal team said regarding the jury, signaling their hope that at least one juror will raise doubts about the theories presented by the prosecution.
