"I'm going to start with something I can say i think with confidence … which is just to thank you. To thank you for your jury service," defense attorney Todd Blanche told jurors to begin his closing argument.

"Each of you will decide ... whether President Trump is guilty or not guilty," he said.

All eyes in this courtroom are on Blanche. Every member of Trump's family is looking at him. The jurors are staring at him, many with pens in their hands ready to take notes.

"President Trump is innocent," Blanche said. "He did not commit any crimes, and the district attorney has not met their burden of proof. Period."

Defense counsel Todd Blanche says he has a 2.5-hour closing, "maybe a little longer."

Prosecutors say they estimate they have a 4 or 4.5-hour closing.

“Defense counsel must come up first, and the prosecutor must follow,” Judge Merchan said.

Merchan says he will ask the jury if they will work later than 4:30 p.m. to do all the closings in one day.

Judge Juan Merchan has taken his seat at the bench.

"Good morning, counsel. Good morning, Mr. Trump," Merchan said in his normal greeting to start the proceedings.

Donald Trump has entered the courtroom alongside his lawyers.

Don Trump, Jr., Eric Trump, Lara Trump, and Tiffany Trump followed behind the former president and took seats in the gallery immediately behind the defense counsel table.

Today is the first time Tiffany Trump attended the trial, and it's the largest showing of Trump family members on a single day of the trial.

Manhattan DA Alvin Bragg, also in court today, is seated behind his prosecution team.

The first hour of prosecutor Josh Steinglass' summation sounded impromptu, as if he was extemporaneously delivering a direct response to the defense's closing.

As his closing entered its second hour, Steinglass unveiled a slideshow and timeline to make his argument -- slowing down the pace of his delivery and bringing the jury back to the first witness in the case, former National Enquirer publisher David Pecker.

Steinglass walked the jury through the $30,000 payment American Media Inc. made to doorman Dino Sajudin for the rights to his false story about Trump having a child out of wedlock. He outlined timeline of the catch and kill, emphasizing the steps taken to ensure Sajudin did not become a problem for the campaign.

According to Steinglass, Cohen added a $1 million breach of contract penalty "just to put the fear of God into Sajudin."

"Mr. Sajudin had been completely neutralized as a threat to the campaign," Steinglass said about the payment.
