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.

After court resumed for the afternoon session, David Pecker retook the stand.

The former National Enquirer publisher testified that six months after Donald Trump became president, Trump hosted a "thank-you dinner" for Pecker and some of his business associates.

After taking photos in the Oval Office -- "Jared Kushner was there, Sean Spicer was there" Pecker said -- Trump asked Pecker to walk with him along the colonnade "past the Rose Garden," Pecker recalled. The jury saw a photo of the two men on that walk.

Trump said that on that walk, Trump asked Pecker, "How's Karen doing?" referring to Karen McDougal, who the National Enquirer had paid to catch-and-kill her story claiming a year-long relationship with Trump.

"She's doing well. She's quiet. All's going good," Pecker recalled responding.

Eight months later, in March 2018, Pecker said Trump called him about a television interview McDougal had conducted.

"He said 'Did you see the Anderson Cooper interview with Karen McDougal?' I said yes. He said, 'I thought we had an agreement with Karen that she can't give any interviews or be on any television shows.' So I said yes we have an agreement, but I amended it," said Pecker, who testified earlier that he had done so following the election.

Pecker testified that Trump was very upset. "He couldn't understand why," Pecker said. "He couldn't believe that I did it."

Pecker said Trump also called him after Stormy Daniels appeared on a television interview a short while later.

"He said, 'We have an agreement with Stormy Daniels that she cannot mention my name or do anything like this, and each time she breaches the agreement it's $1 million penalty,'" Pecker said.
