Judge Merchan instructed the jury about how to decipher intent, telling them it "does not require premeditation."

Intent can even be momentary, Merchan said, telling the jurors the question about how to judge intent "naturally arises."

"You must decide if the required intent can be inferred beyond a reasonable doubt," he told them.

Merchan also said earlier, "If it is proven the defendant is criminally liable for the conduct of another, the extent or degree of defendant's participation does not matter ... The defendant is as guilty of the crime as if he had personally omitted the crime."

Judge Merchan told jurors that Michael Cohen is an "accomplice" to the alleged crime, so the jury cannot convict Trump on Cohen's testimony alone.

Even if they believe Michael Cohen, they need to rely on evidence corroborating his testimony, Merchan said.

Trump, at the defense table, appeared to perk up just a bit at this, looking up at Merchan as he delivered this information to the jury.

Judge Merchan told the jury that they have the ultimate authority in determining the truthfulness of a witness' testimony -- an instruction that might come in handy given the emphasis that defense lawyers placed on Michael Cohen's testimony, which they say includes lies.

"You will alone determine the truthfully and the accuracy of the testimony of each witness," Merchan said.

He added that the jury could either disregard the testimony of an untruthful witness entirely, or disregard part of it.

"There is no particular formula" to determine credibility, Merchan said.

"You may consider whether the witness has any interest in the outcome of the case," he said -- another matter that might weigh on jurors' minds.

"You may consider whether a witness did have, or did not have, a motive to lie," the judge said.

Trump's attorney had told the jury Cohen had an "axe to grind" against his former boss. Prosecutors partially conceded that Cohen had a motive, acknowledging that, to date, he is the only one who suffered any consequences from the matter at hand.

Trump, at the defense table, appeared to look over to the jury and offer a bit of a closed-mouth grin.

Judge Merchan instructed the jury that they cannot hold Trump's not testifying against him.

"Defendant is not required to prove that he is not guilty," he said.

"The defendant is not required to prove or disprove anything," said the judge.

Finishing up his 10 reasons why he says Trump should be acquitted, defense attorney Todd Blanche listed:

- "There is no evidence of any illegal effort to influence the 2016 election," Blanche said.

- "AMI would have run Mr. Sajudin's story no matter what," Blanche said. "That's not catch and kill."

- "McDougal did not want her story published," Blanche said. "That's not catch and kill."

- Daniel's story was "already public," Blanche said.

- Blanche argued that key evidence was "manipulated" during the trial. He alleged that the district attorney's office made mistakes when analyzing Cohen's phone. "How can you trust that the September 6 recording is actually reliable? The answer is you can't," Blanche said.

- "Michael Cohen. He is the human embodiment of reasonable doubt," Blanche said.

In a play on words, Blanche asked the jurors if the knew of the term GOAT, for the Greatest Of All Time. Some of them nodded.

He then said Cohen was the GLOAT, the "greatest liar of all time."

"You cannot send someone to prison based upon the words of Michael Cohen," Blanche said, concluding his closing statement.
