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.

While the jury deliberates, Trump -- from the courthouse -- posted to social media about the readback that the jury just heard.

During the readback, the jury heard former National Enquirer publisher testify about a June 2016 phone call he had with Trump after Playboy model Karen McDougal came forward with a story of a year-long affair with Trump, which Trump has steadfastly denied.

"This story about Karen, since she's claiming that she has a relationship with you, should be taken off the market," Pecker recounted telling Trump -- to which Trump replied, "I don't normally -- I don't buy stories because it always gets out."

"I still think you should buy the story," Pecker testified that he told Trump, to which Trump replied, "I'll speak to Michael, and he'll get back to you."

In his social media post, Trump said, "Testimony conclusively showed that I clearly stated, "I DON'T BUY STORIES!" -- Not that there would be anything wrong with doing that -- NDA's [nondisclosure agreements] are PERFECTLY LEGAL AND COMMON!"

Pecker testified that the National Enquirer eventually paid McDougal $150,000 to catch and kill her story so it would not become public, under the expectation that the money would be reimbursed by Trump -- although the reimbursement never materialized.
