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."

The combative hearing on Trump's alleged violations of the judge's limited gag order ended with the judge saying he will not rule from bench on the district attorney's motion to hold Trump in contempt, so a ruling will come later.

Before concluding the hearing, Judge Merchan told Trump attorney Todd Blanche, "You're not offering me anything … to hang my hat on."

The trial will resume shortly with the return of former National Enquirer publisher David Pecker to the witness stand.

Judge Juan Merchan is visibly irritated with the lack of evidence presented by defense attorney Todd Blanche.

"You have presented nothing," Merchan said. "I have asked eight or nine times; show me the exact post he was responding to."

"You're losing all credibility with the court," Merchan said after Blanche suggested Trump has been careful to comply with the gag order.

Blanche attempted to represent that Trump did not intend to violate the gag order, but Merchan did not appear satisfied by the response.

"Are you testifying under oath that this is his position?" Merchan asked.

"Do you want me to put him on the stand?" Blanche asked, though Trump did not take the stand.

Merchan strongly reacted earlier when Blanche suggested there were two tiers of justice in the courtroom.

"There are two systems of justice. Mr. Weisselberg is in prison, and Mr. Cohen is a witness," Blanche said, in reference to the former Trump Organization CFO who was sentenced to jail time for perjury.

"There are two systems of justice in this courtroom -- is that what you are saying?" Merchan responded.

The contempt hearing has turned tense as Trump attorney Todd Blanche tries to defend Trump's posts as mere responses to attacks -- but isn't giving clear examples of how Trump was being attacked.

Instead, Blanche asked the judge why the timing of the posts mattered -- prompting a strong rebuke from the judge.

"I'm asking the questions, OK?" Judge Merchan told Blanche. "Please don't turn it around."

Merchan continued to reprimand Blanche: "I'm asking a specific question over and over and I'm not getting an answer."

Merchan then lamented that nearly an hour into the hearing they are still only up to reviewing post NO. 2 of 10, and the jury is set to arrive at 11 a.m. ET to resume trial proceedings.

"The people got to speak as long as they want to," Blanche said regarding the prosecutors.

"The people were answering my questions," Merchan retorted.

So far, Merchan has appeared skeptical of what Blanche has been arguing in defense of the posts. Blanche at times has been struggling to answer Merchan's questions, at one point saying, "I don't have any case law to support that. It's just common sense."

Asked to share her responses to the jury questionnaire, one prospective alternate said she wanted to "jump ahead" to Question 34, which asks whether any strong opinions of Trump would interfere with the ability to be fair.

"The last day, after some introspection, I don't think I can be impartial," the woman said. "I had every intention when I first started, but I think after the questions posed to prospective jurors and asking the questions to myself, I don't think I can be impartial."

Judge Merchan excused her without objection from the attorneys.

A prospective alternate who works for the New York City Law Department said in response to a question that she had read Trump's "Art of the Deal." Trump, who appeared to have his eyes closed, opened them right away at that response and looked at the woman.

The woman also said she had been sexually assaulted "a couple of times on the train."

Trump also appeared to have been chewing on something. He has been conferring with defense attorney Emil Bove throughout the more mundane parts of the questionnaire responses.

A chef for a "large hospitality group" said he follows the White House account on Instagram, "so when Mr. Trump was president, obviously I was receiving updates." Trump turned his head to look at the man after he had been slumped over the defense table looking down.
