At least 50 of the 96 potential jurors in the first group have been excused from service after they identified that they can't be fair or impartial regarding the case.

Judge Merchan is now beginning the process of questioning the remaining jurors.

During his lengthy remarks to potential jurors regarding the case, Judge Merchan listed several individuals who could potentially be called as witnesses at trial -- but emphasized that not all would be summoned to the stand.

Among those Merchan listed as potential witnesses were Trump, Stormy Daniels, and former Trump attorney Michael Cohen, as well as David Pecker, the former American Media Inc. executive who prosecutors say played an integral role in a plan to "catch and kill" negative stories about Trump in 2016.

Several Trump family members were also named, including Melania Trump, Eric Trump, Donald Trump Jr., Jared Kushner and Ivanka Trump.

Other potential witnesses listed were former members of Trump's administration, including Steven Bannon, Kellyanne Conway, Reince Priebus, Hope Hicks and John McEntee.

Merchan also listed a number of former employees of the Trump Organization, including Allen Weisselberg, Jeffrey McConney, Dan Scavino, Rhonna Graff and Alan Garten. Additional names mentioned included Robert Costello, Keith Davidson, and Rudy Guliani.

As Judge Merchan reviewed the details of the case for the first group of 96 prospective jurors, former President Trump turned and faced the group -- eliciting visible responses from the gallery.

One woman let out an audible giggle, covered her mouth, and looked to her neighbor with eyebrows raised. Others craned their necks from the rear of the courtroom to catch a glimpse of the defendant.

Trump earlier had his eyes locked on Merchan as the judge went through his instructions to the group.

The former president subsequently appeared to close his eyes and fold his arms, sporadically adjusting in his seat.

The first group of 96 prospective jurors has been sworn in.

Judge Merchan is now delivering remarks that he said will last about 30 minutes, introducing the case and explaining to prospective jurors their responsibility -- if selected -- to be fair and impartial.

Trump has been leaning forward in his seat listening, with his elbows on the desk.

As jury selection resumed for the afternoon session, Judge Juan Merchan scolded former President Trump over his audible "muttering" while a prospective juror was speaking.

"Your client was audibly muttering something," the judge told Trump's attorneys. "He was speaking in the direction of the juror. I will not tolerate that. I will not have any jurors intimidated in this courtroom. I want to make that crystal clear. Take a minute and speak to your client."

The interaction occurred after Trump's defense attorney sought to immediately strike potential jurors for cause based on social media posts that he said contradicted their assertions of fairness.

"There's a number of the jurors that we have social media posts for very much contrary to the answers that they gave," defense attorney Todd Blanche said.

Blanche pointed to a woman who he said has a "series of extraordinarily hostile Facebook posts."

One of the posts read, "So I've been in the middle of the ocean for the last few weeks. What's going on?"

Another post included a video of people celebrating near Manhattan's 96th Street and the words, "Full-on dance party at 96 Street."

Judge Merchan seemed baffled. "Show me the bias," the judge said. "I'm trying to understand. How does this call into question what the juror said when that juror was answering questions?"

Blanche insisted the post, a day after the 2020 election, was a celebration of Trump's loss.

"This is ridiculous," prosecutor Josh Steinglass said.

The judge determined "there are enough questions here" to allow the defense to question the woman about her posts.

"I think I went to the car to alternate-side parking or something like that and there were people dancing in the street," the woman said, adding that it reminded her of the pandemic-era cheer for health workers.

"I understand that bias exists," the woman said. "The job of the juror is to understand the facts of the trial."

When the woman left the room, that's when the judge scolded Trump.
