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."

Former National Enquirer publisher David Pecker testified that he was twice summoned to Trump Tower in the period following the 2016 election: the first time for a meeting with Michael Cohen, and the second with Donald Trump.

The first meeting began in Cohen's office, where Cohen divulged for the first time to Pecker that he personally covered the $130,000 payment to Stormy Daniels, and that he was concerned that he would not receive a bonus from the Trump Organization, Pecker testified.

"He (Cohen) asked me to talk to the boss on his behalf to try to help him get his bonus," Pecker said, referring to Trump.

When Trump himself came into the room, Pecker asked to walk him back to his office -- and at that time, Pecker told Trump that "Michael Cohen is very concerned about his bonus for this year, and I want you to know that he's very loyal."

Trump replied that Cohen had several apartments and taxi medallions, and added, "Don't worry about it, I'll take care of it," Pecker said.

On Jan. 6, 2017, Pecker arrived at Trump Tower for a meeting with Trump and was escorted to his residence by Jared Kushner, he testified.

Pecker said he was ushered into the room, where Trump was surrounded by administration officials James Comey, Sean Spicer, Reince Priebus, and Mike Pompeo -- they were "updating Mr. Trump on the Ft. Lauderdale shooting" that had occurred at the airport there.

Pecker testified that when Trump introduced him to Trump's inner circle of advisers, Trump said of the National Enquirer publisher, "He knows more than anyone else in this room."

"It was a joke. Unfortunately, they didn't laugh," Pecker testified, which brought some laughs from reporters in the gallery. A few jurors smiled at the moment.

Pecker testified that after Trump's advisers left the room, Trump turned to him.

"He (Trump) asked me how Karen [McDougal] was doing -- how's 'our girl' doing. I said, she's writing her articles, she's quiet, things are going fine."

Trump then said, "I want to thank you for handling the McDougal situation." And then he said, "I want to thank you for the doorman situation," Pecker testified.

Pecker testified that he took this to mean that Trump was thanking him "for not publishing any of the stories and helping the way I did."
