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.

In June of 2016, as the National Enquirer evaluated the merits of Karen McDougal's claim of a year-long affair with Trump, Trump's attorney Michael Cohen instructed Pecker to purchase her story -- and suggested that Trump would compensate the company for the cost, according to Pecker.

Pecker recalled from the stand a conversation he had with Cohen, in which Cohen told him, "You should go ahead and buy this story."

"So I said to him … 'Who's going to pay for it?'' Pecker testified, saying Cohen replied, "'Don't worry, I'm your friend, the boss will take care of it.'"

Pecker said he interpreted that to mean that if the National Enquirer purchased the story, Trump or the Trump Organization would reimburse him.

Picking up on his testimony from Tuesday, Pecker said that when he spoke with Trump about McDougal's story, he recalled that Trump called McDougal "a nice girl" and asked Pecker what he should do about it.

"I think you should buy this story and take it off the market," Pecker said, explaining that he "believed the story was true. I think that it would be embarrassing to himself and also to his campaign."

During her negotiations with the National Enquirer, McDougal represented that "she didn't want to be the next Monica Lewinsky," Pecker said.
