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."

"Karen McDougal was a Playboy model," former National Enquirer publisher David Pecker said, recalling how he learned in June 2016 "that there's a Playboy model who is trying to sell a story about a relationship that she had with Donald Trump for a year."

Pecker said he immediately called Trump's then-attorney Michael Cohen to inform him. By then, he was speaking to Cohen "a couple times a week," but that soon changed. Pecker said he and Cohen spoke "much more frequently" about McDougal's claims.

"Michael was very agitated. It looked like he was getting a lot of pressure to get the answer right away," Pecker said. "He kept on calling, and each time he called he seemed more anxious."

Pecker said he assumed "Mr. Trump was asking Michael Cohen, 'Did we hear anything yet?'" Pecker said.

"Did you ever come to believe that Michael Cohen had spoken with Mr. Trump about McDougal's claims?" prosecutor Josh Steinglass asked.

"Yes I did," Pecker responded before recounting a phone conversation Pecker said he himself had with Trump.

"I said I think the story should be purchased and we should buy it," Pecker recalled telling Trump. "Mr. Trump said to me, 'I don't buy stories. Anytime you do anything like this, it always gets out.'"

Ultimately, McDougal was paid $150,000 and promised a series of exercise articles in the publication.

Following that testimony, court was adjourned.

It's expected the jury will hear more on McDougal upon Pecker's return to the witness stand, when court resumes on Thursday.
