Nine additional prospective jurors from the second group of 96 were excused after they signaled they could not serve for other, unexplained, reasons.

Fifty-seven of the 96 in the second pool of prospective jurors have now been excused.

The remaining 39 are now giving their responses to the seven-page questionnaire.

Following the departure of Juror No. 2 this morning after she expressed concerns about her ability to serve, the court must now seat six jurors and six alternates. The court deferred dealing with the potential issue over Juror No. 4.

Addressing the new group of 96 prospective jurors, Judge Merchan asked for a show of hands "if you believe you cannot be fair and impartial."

Forty-eight people -- half the pool -- raised their hands.

Those potential jurors were then excused from the courtroom as Trump turned around to stare at those behind him.

A new group of 96 prospective jurors has entered the courtroom for the next round of jury selection.

Several in the group registering surprise upon seeing Trump at the defense table.

As Judge Merchan delivered his opening remarks, Trump’s eyes often remained closed. He appeared more attentive when Merchan ticked through the names of potential witnesses, which read like a Who’s Who of the Trump family, campaign and administration.

Following the loss of Juror. No. 2, attorneys are now discussing an issue with yet another juror -- Juror No. 4 -- after Assistant District Attorney Joshua Steinglass said the the DA's team did research that "possibly called into question the veracity" of the answers he gave on the jury questionnaire.

Steinglass said a person with the same name as Juror No. 4 -- the Puerto Rican man who said he found Trump "fascinating and mysterious" -- had been arrested in the 1990s in Westchester for "tearing down political advertisements."

“I actually believe the propaganda that was being ripped down was political posters that were on the right -- the political right," Steinglass said.

He suggested that Juror No. 4's answer to question 19 on the questionnaire -- if you have ever been accused or convicted of committing a crime -- then "was not accurate."

Steinglass added they discovered the juror's wife had been embroiled in a "corruption inquiry" that resulted in her "entering in a differed prosecution agreement ... with the Manhattan DA's office."

Steinglass said they felt they were "ethically and legally obligated to bring this information to the court."

Judge Merchan said he instructed Juror No. 4 to be in court at 9:15, but he still has not shown up.

Trump attorney Todd Blanche said he did not consent to dismissing the juror without first hearing from him. They will revisit the issue later.

The U.S. Secret Service has held meetings and started planning for what to do if former President Trump were to be held in contempt and Judge Juan Merchan opted to send him to short-term confinement, officials familiar with the situation tell ABC News.

Prosecutors said at this point they are seeking a fine.

"We are not yet seeking an incarceratory penalty," assistant district attorney Chris Conroy said, "But the defendant seems to be angling for that."

Officials do not necessarily believe Merchan would put Trump in a holding cell in the courthouse but they are planning for contingencies, the officials said.

There have be no discussion about what to do if Trump is convicted and sentenced to prison, they said.

"Under federal law, the United States Secret Service must provide protection for current government leaders, former Presidents and First Ladies, visiting heads of state and other individuals designated by the President of the United States," the Secret Service said in an official statement. "For all settings around the world, we study locations and develop comprehensive and layered protective models that incorporate state of the art technology, protective intelligence and advanced security tactics to safeguard our protectees. Beyond that, we do not comment on specific protective operations."
