After a break, Judge Merchan ruled that prosecutors can submit evidence related to Trump's attacks on his former attorney Michael Cohen if the defense first chooses to question Cohen's credibility as a witness.

Merchan said, "I imagine" the defense will seek "to discredit" Cohen -- and when they do, he said, "the door is open" for prosecutors to introduce those tweets of Trump's.

Trump has been leaning forward with his hands clasped beneath his chin as his attorney, Todd Blanche, argues about what other evidentiary guardrails should be in place.

Following the arguments over alleged witness intimidation, prosecutors signaled they may seek to have Trump held in contempt.

A limited gag order Judge Merchan imposed in recent weeks prohibits Trump from attacking witnesses and others associated with the case.

"Shortly, we will be seeking order to show cause as to why defendant should not be held in contempt," prosecutor Josh Steinglass said, suggesting Trump violated Merchan's order.

Prosecutor Joshua Steinglass argued that several pieces of evidence related to Trump's alleged "pressure campaign" meant to "keep witnesses off this stand, at this trial" should be introduced at trial.

Steinglass said Trump's public commentary amounted to a "thinly veiled effort to intimidate" two of the government's star witnesses, Michael Cohen and Stormy Daniels.

"The defendant himself has publicly embraced the public strategy of going after his perceived enemies," Steinglass said.

"These tweets, phone calls and emails" should be permitted, Steinglass said. "It's a clear effort to raise the cost of cooperation."

Trump's public postings, Steinglass argued, demonstrate Trump's attempts to silence potential fact witnesses and "relate to his consciousness of guilt."

Trump attorney Todd Blanche pushed back, saying that Trump has been "facing criticism from all sides … the media and others ... and he's defending himself" to his "millions and millions of followers."

Judge Merchan declined to allow prosecutors to introduce the sexual misconduct allegations a number of women made against Trump during the closing weeks of the 2016 campaign, deciding they're "complete hearsay."

However, Merchan said prosecutors are allowed to show the jury videotaped clips of Trump from some of his campaign events in which he appears agitated about some of the allegations.

"This concern over losing female voters was the catalyst for the defendant to lock down the Stormy Daniels story before it became the straw that broke the camel's back," prosecutor Josh Steinglass argued.

The defense said unproven accusations of other women whose claims are not part of the criminal trial are "a very prejudicial sideshow."

The judge agreed that introducing the allegations themselves would not be fair to Trump, but he told prosecutors "You can still use those tapes" of Trump's campaign appearances. The former president has denied all such allegations.

Trump is leaning back in his chair as he listens to this throwback to the chaotic close of the 2016 campaign, frequently leaning in to tap defense attorney Todd Blanche on the arm to get his attention and then whispering something into his ear.

As jury selection resumed for the afternoon session, Judge Juan Merchan scolded former President Trump over his audible "muttering" while a prospective juror was speaking.

"Your client was audibly muttering something," the judge told Trump's attorneys. "He was speaking in the direction of the juror. I will not tolerate that. I will not have any jurors intimidated in this courtroom. I want to make that crystal clear. Take a minute and speak to your client."

The interaction occurred after Trump's defense attorney sought to immediately strike potential jurors for cause based on social media posts that he said contradicted their assertions of fairness.

"There's a number of the jurors that we have social media posts for very much contrary to the answers that they gave," defense attorney Todd Blanche said.

Blanche pointed to a woman who he said has a "series of extraordinarily hostile Facebook posts."

One of the posts read, "So I've been in the middle of the ocean for the last few weeks. What's going on?"

Another post included a video of people celebrating near Manhattan's 96th Street and the words, "Full-on dance party at 96 Street."

Judge Merchan seemed baffled. "Show me the bias," the judge said. "I'm trying to understand. How does this call into question what the juror said when that juror was answering questions?"

Blanche insisted the post, a day after the 2020 election, was a celebration of Trump's loss.

"This is ridiculous," prosecutor Josh Steinglass said.

The judge determined "there are enough questions here" to allow the defense to question the woman about her posts.

"I think I went to the car to alternate-side parking or something like that and there were people dancing in the street," the woman said, adding that it reminded her of the pandemic-era cheer for health workers.

"I understand that bias exists," the woman said. "The job of the juror is to understand the facts of the trial."

When the woman left the room, that's when the judge scolded Trump.
