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.

Despite first meeting Michael Cohen by chance in 2000 at a bar mitzvah, former National Enquirer publisher David Pecker testified that Donald Trump first introduced him to Cohen as his personal lawyer in 2007.

Pecker said Trump asked him to begin coordinating with Cohen about any stories or rumors related to Trump or his family.

"All of the contacts that I had with Mr. Trump -- now my contact should go through Michael Cohen," Pecker said about Trump's directive after meeting Cohen.

Pecker and Cohen would touch base monthly over the following decade, but communications ramped up after Trump announced his candidacy for president in 2015, Pecker said.

"I would say a minimum of every week, and if there was an issue, it could be daily," Pecker said about his contact with Cohen during the campaign.
