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.

Trump attorney Todd Blanche, responding to prosecutors' request for Judge Merchan to fine Trump for three social media posts they say violated the judge's limited gag order, characterized the posts as "limited responses to this barrage of attacks" against him by Stormy Daniels and Trump's former attorney Michael Cohen.

"It's not as if President Trump is going out and targeting individuals. He's responding to … attacks from these witnesses," Blanche said.

The three posts by Trump -- two on April 10 and a third on April 13 -- came just days before the trial.

In one of those posts, Trump thanked Daniels' former attorney, Michael Avenatti for "revealing the truth about two sleaze bags" -- a statement prosecutors say clearly "attacks" Daniels and Cohen and their participation in the trial.

Judge Merchan said Blanche would have an opportunity to respond in a paper filing.

"I'll take this upstairs with me over the lunch recess," Merchan said.

The judge then recessed court until 1:30 p.m. ET.
