"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.

Prosecutor Josh Steinglass told jurors that allegations from women in October 2016 posed a significant risk to Trump's campaign.

"This race could not have been closer," Steinglass said, arguing that Trump knew the allegations were "capable of costing him the whole election, and he knew it."

Steinglass replayed a video of an October 2016 Trump rally in Greensboro, North Carolina to demonstrate Trump's concern.

"It caused pandemonium in the Trump campaign," Steinglass said about the "Access Hollywood" tape.

Trump, at the defense table, looked at the evidence before shifting back in his chair. After shaking his head in disagreement, he whispered back and forth with his attorney Emil Bove.

Steinglass argued that Trump was particularly concerned about the Daniels allegations because they could undermine his response to the "Access Hollywood" tape.

"Stormy Daniels was a walking, talking reminder that the defendant was not only words," Steinglass said. "She would have totally undermined his strategy for spinning the 'Access Hollywood' tape."

Hitting back at the defense's suggestion that the "Access Hollywood" tape "wasn't a big deal to the defendant -- it was just another blip," Steinglass said, "You really can't understand this case without appreciating the climate in the wake of the 'Access Hollywood' tape ... it caused pandemonium in the Trump campaign."
