Prosecutors are keeping their cards close to vest regarding who the first witnesses called at trial will be.

When defense attorney Todd Blanche requested the names of the first three state witnesses, prosecutor Joshua Steinglass declined to provide the name of the first planned witnesses following opening statements.

“Mr. Trump has been tweeting about the witnesses,” Steinglass said. “We are not telling you who the witnesses are.”

Blanche attempted to ease that concern by vowing that the former president would not post about the likely witness.

“I don’t think you can make that representation,” Judge Juan Merchan said.

On a separate matter, Merchand said that if time permits tomorrow, he plans to hold a planned hearing on the bounds of Trump’s cross-examination if he opts to testify.

Judge Merchan indicated that his goal is to have opening statements in the trial begin on Monday morning.

“We can't start until every single one of you is here,” Merchan said to the newly sworn-in jury members, urging them to inform him if they encounter any delay.

After the jury was sworn in, former President Trump sat stone-faced at the defense table with his hands locked, staring at the jury as they left the courtroom.

Following the seven jurors chosen earlier, here is basic biographical information on the remaining five jurors, whose identities are being kept private for security reasons.

Juror No. 8 is a former wealth manager who moved to New York in the 1980s. He is originally from Lebanon.

Juror No. 9 is a speech therapist who grew up in New Jersey.

Juror No. 10 has lived in Murray Hill for six years and worked in commerce for an eyewear company.

Juror No. 11 is originally from California and works as a production development manager for a multinational apparel company.

Juror No. 12 is a physical therapist whose husband works as a coach for a professional sports team.

A full jury of 12 members has now been seated following the addition of five more jurors.

The court is now working to select the six alternate jurors for the case.

"We have our jury," Judge Merchan said.

The 12 jurors then rose, raised their right hands, and were sworn in.

Former National Enquirer publisher David Pecker, back on the witness stand, pointed at Donald Trump and flashed a smile when he was asked to identify the defendant. Trump turned his chin up and grinned at his longtime friend.

"I met Mr. Trump at Mar-a-Lago," Pecker said. "I've had a great relationship with Mr. Trump over the years."

That relationship started in 1989 when Pecker wanted to start a magazine called Trump Style.

"He was very helpful in introducing me to other executives in New York. He would always advise me of parties or events that I would go to," Pecker said, adding that Trump was among the first to congratulate him upon acquiring the National Enquirer.

Pecker described how Trump became a "major celebrity" after launching The Apprentice and later Celebrity Apprentice, and how the National Enquirer was there to juice Trump's profile.

"He was always kind enough to send me the content showing the ratings and I was able to publish that," Pecker said of their "great mutual beneficially relationship.

Pecker said he considered Trump a friend from 2015 to 2017, calling him by the familiar "Donald," as he pursued the White House for the first time.

"After he announced his run for the presidency I saw Mr. Trump more frequently, maybe once a month," Pecker said. The two spoke "maybe once every couple of weeks."

Pecker recalled meeting Trump in his office when his assistant brought a batch of invoices and checks to sign.

"As I recollect the entire package was stapled together," Pecker said.

"So you observed him reviewing an invoice and signing a check?" prosecutor Josh Steinglass asked. "That's correct," Pecker responded.

"I would describe him as very knowledgeable, very detail-oriented, almost as a micromanager," Pecker said.

When Steinglass asked how Trump was with money, Pecker responded, "He was very cautious and very frugal."
