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.

Former National Enquirer publisher David Pecker retook his seat on the witness stand after lunch, and the jury appeared engaged when prosecutor Josh Steinglass asked Pecker to explain things directly to them. Pecker slightly turned to face the jury when answering.

After the defense, during cross-examination, tried to suggest Pecker didn't want to get involved in the Stormy Daniels story for business and reputational reasons, Steinglass asked him to clarify.

"I said to Michael Cohen that after paying for the doorman story and the Karen McDougal story I wasn't going to pay anything further and I wasn't a bank," Pecker testified. "I told (editor) Dylan Howard there is no possible way that I would buy the story for $120,000 and that I didn't want anything to do with a porn star."

Steinglass asked Pecker, "Why did you reach out to Michael Cohen" about Daniels' claim of a sexual liaison with Trump?

"Based on our original agreement, any stories regarding Mr. Trump that could be embarrassing, I would call Michael Cohen right away," Pecker said.

"You weren't going to print it? You weren't going to pay for it?" Steinglass asked.

"Correct," Pecker responded.

"But you were still going to fulfill your obligation to tell Michael Cohen about it? So the campaign could squash it?" asked Steinglass.

"Yes," Pecker responded.
