"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.

Defense attorney Todd Blanche told jurors that Michael Cohen's one-time legal adviser Robert Costello -- the only substantive defense witness -- offered testimony to demonstrate that Cohen lied on the witness stand.

Blanche argued that Cohen lied about what he asked of Costello and how often they communicated.

"It's just another example of Mr. Cohen taking the witness stand and lying to you," Blanche said, suggesting that Cohen lied on the stand enough times that the jury should consider throwing out his entire testimony.

"I don't know how many lies are enough lies just to reject Mr. Cohen's testimony ... big or small, meaningful or not meaningful, but that was a lie," Blanche said.

Blanche argued that prosecutors attempted to prop up Cohen's credibility by offering phone records to corroborate his testimony, but the strategy backfired.

"They showed him phone records and they showed him calls between him and others to help his testimony seem more corroborate and more credible," Blanche said. "We all know how that ended."

Raising his voice, Blanche reminded the jury about the inconsistency he highlighted in Cohen's testimony about a October 24, 2016, phone call.

"It was a lie!" Blanche shouted. "That was a lie and he got caught red-handed!"

"That is perjury!" Blanche shouted, drawing out each syllable.

"They are perfectly happy to have a witness commit perjury to lie to you," Blanche said, prompting an objection from prosecutors.

"Sustained," said Judge Merchan.
