Judge Juan Merchan took his seat on the bench and began the day's proceedings.

After introductions from the lawyers, Merchan said his usual, "Good morning, Mr. Trump."

Before Merchan entered the courtroom, one of the court officers left a document on the bench and handed copies to both parties.

Former President Trump has entered the courthouse for the day's proceedings.

The prosecution team has arrived in the courtroom. Prosecutor Josh Steinglass was seen reviewing documents with a court reporter.

Ahead of the start of deliberations this morning, court stenographers are sorting through seven enormous transcript binders that are scattered around the jury box.

With the jury requesting readbacks of testimony, the transcripts are set to play a key role in this morning's proceedings.

About 60 members of the press are packed into the gallery ahead of the proceedings.

As jurors begin their second day of deliberations, Trump's legal team feels that the longer the jury deliberates, the more they're hoping for a hung jury, sources told ABC News.

Trump's lawyers see the requests the jury has made to rehear testimony from the case as a mixed bag, the sources said -- not positive news that jurors wanted to rehear former National Enquirer publisher David Pecker's testimony, but at the same time feeling optimistic that jurors requested portions of Michael Cohen's transcript.

Trump's attorneys are looking for any indication that the jury will probe issues surrounding Cohen's credibility, which cuts to the core of their defense, according to the sources.

"We want chaos ... we want evidence of strong disagreements," one person close to Trump's legal team said regarding the jury, signaling their hope that at least one juror will raise doubts about the theories presented by the prosecution.

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.
