Donald Trump, addressing the media ahead of this afternoon's pre-charge conference, told reporters, "This next couple of hours is very important."

Judge Juan Merchan is preparing to hear arguments from attorneys regarding the instructions the judge will provide jurors about the law and evidence in the case when the jury begins deliberating next week.

Trump declined to answer questions from the reporters about why he decided not to testify in the case, and whether he is nervous about a possible conviction.

Judge Merchan asked the parties to return to the courtroom at 2:15 p.m. ET. for the previously scheduled pre-charge conference.

It will provide an opportunity for the parties to weigh in on the instructions Merchan will provide the jury about the law and evidence in the case.

Trump and his entourage then filed out of the courtroom.

Following the defense resting its case, Judge Juan Merchan told the parties that "summations will not be quick" and that they "will take at least a day." Jury instructions will then take at least an hour, he said.

"At the end of the day, I think the best thing we can do is to adjourn now until next Tuesday. At that time you will hear summations from the attorneys," Merchan said.

Merchan says that deliberations could begin as early as next Wednesday.

Merchan told the jury he opted to delay the summations because of this week's abbreviated schedule and his belief that "it's always ideal or best not to break up summations."

Trump's eyes were closed, his head titled back, as Merchan instructed the jury to return on Tuesday.

The jury then left the courtroom.

"You still have a lot of animosity against Michael Cohen," prosecutor Susan Cohen Hoffinger asked Michael Cohen's then-legal adviser Robert Costello after displaying emails from 2018.

"I don't have animosity but --," Costello replied before being cut off.

"Yes or no," Hoffinger said.

Hoffinger then asked Costello bluntly if he was trying to "intimidate" Cohen regarding his 2018 congressional testimony.

"Intimidate Michael Cohen?" Costello asked incredulously.

"Yes, that's my question," Hoffinger repeated firmly.

"Ridiculous, no," Costello responded.

Hoffinger then concluded her cross-examination, which was followed by a brief redirect.

"Your honor, the defense rests," the defense team told Judge Merchan.

Former President Trump did not end up taking the stand in his own defense.

Judge Merchan denied a request from defense lawyers to broaden the scope of testimony from their expert witness Bradley Smith, who is an expert on campaign finance regulations.

On Thursday, defense lawyers asked Merchan to allow Smith to testify about various terms related to federal campaign finance laws. Merchan denied the request, citing long standing precedent prohibiting witness testimony about the law.

"An expert is not permitted to present or interpret the law," Merchan said.

Merchan also expressed concerns about Smith's testimony prompting a "battle of the experts" between Smith and an expert called by prosecutors, which Merchan said would confuse the jury.

Merchan said that Smith could still testify, as long as he follows the limits imposed in his pretrial ruling on the case's motions in limine.

"The court will monitor this testimony closely to ensure full compliance," Merchan said in a pretrial ruling. "Any deviation from this ruling could result in sanction up to and including striking the expert's entire testimony."

Trump, sitting at the defense table, shook his head after the judge announced his ruling.
