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.

A day after Judge Judge Juan Merchan threatened to remove him from the witness stand, former federal prosecutor Robert Costello will resume his testimony this morning as the second witness in Donald Trump's defense case.

Costello is expected to be the final defense witness before Trump's lawyers rest their case today.

Yesterday, Costello told jurors about his meetings and phone calls with Michael Cohen in 2018 after FBI agents raided his office and hotel room. Costello advised Cohen and helped pass messages to the Trump, according to Cohen, but never formally represented him as his lawyer.

"Michael Cohen said, numerous times, that President Trump knew nothing about those payments, that he did this on his own, and he repeated that numerous times," Costello testified about the hush money payment to adult film actress Stormy Daniels that sits at the center of the case.

Cohen told the jury that he lied to Costello about Trump's involvement in the scheme to use hush-money payments to hide information from voters.

Costello's reactions to Judge Merchan after taking the stand yesterday afternoon -- responding "jeez" to a sustained objection, rolling his eyes at the judge, and appearing to staring him down -- prompted Merchan to clear the courtroom before threatening to remove Costello from the witness stand.

While defense lawyers suggested yesterday that they would not call Trump to the witness stand, they will likely have to confirm a final decision about the defendant's testimony -- or lack thereof -- before they rest their case.

Judge Merchan has scheduled a charge conference at 2:15 p.m. ET to hear arguments over how to instruct the jury about the law in the case.
