Court is back in session for Day 4 of the trial, kicking off what is widely expected to be the last day of jury selection.

Former President Trump is in his usual seat at the defense table, along with his lawyers. His aide Steven Cheung and attorney Cliff Robert are sitting in the back row of the courtroom.

"Good morning, Mr. Trump," Judge Merchand said as he entered the courtroom, which, like yesterday, is quite chilly.

"We're still working on the temperature in the courtroom," Merchan told all those assembled.

Entering the courthouse this morning, Trump again criticized the limited gag order in the case, telling reporters, "Every time I come out to speak to you, I want to be open because we did absolutely nothing wrong."

It was a continuation of his campaign against Judge Merchan's limited gag order, which prevents him from targeting potential witnesses in the case, as well as jurors, lawyers, court staff, and the families of Merchan and District Attorney Alvin Bragg.

"The gag order has to come off. I should be allowed to speak," he said.

The temperature is rising in Donald Trump's New York criminal trial -- just not in the courtroom itself.

As the parties worked to select the jury Thursday, prosecutors alleged that the former president had violated the limited gag order in the case seven additional times beyond the three instances they flagged on Monday. The accusation came a day after Judge Juan Merchand scolded the former president for muttering within earshot of the jury.

As for the actual temperature, Trump and his attorneys complained it was too cold.

"I'm sitting here for days now from morning till night in that freezing room," Trump told reporters Thursday during a break in the proceedings.

Trump attorney Todd Blanche asked Judge Merchan is he could turn up the heat in the courtroom "just one degree," but the judge politely declined, saying he feared a one-degree bump in the nearly century-old building could increase the temperature by 30 degrees.

But the parties persevered, seating the jury's 12 members by the end of the day. Today they'll work to seat the jury's six alternates, in the hope of starting opening arguments on Monday.

Following court, Trump exited the courtroom where he reiterated to reporters that he spent the day in the courtroom instead of campaigning for president.

"I'm supposed to be in … New Hampshire … I'm supposed to be in Georgia. I'm supposed to be in North Carolina, South Carolina. I'm supposed to be in a lot of different places campaigning, but I've been here all day on a trial that really is a very unfair trial," he said.

The former president went on to claim that legal experts and various media outlets suggest there's no case.

"The case is ridiculous," he said. "It's missing fraud. There is no fraud."

A reporter, referring to a juror who had characterized Trump during questioning as "selfish and self-serving", shouted, "The juror called you selfish. How does that make you feel?" but Trump did not respond and exited the hallway.

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.
