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.

Judge Juan Merchan has recessed court for the day.

Proceedings will resume tomorrow with plans to choose the remaining alternates for the jury.

After a week-long selection process, the jurors in Donald Trump's New York hush money case are scheduled to hear opening statements this morning in the first criminal trial of a former U.S. president.

To prove their case, lawyers for Manhattan District Attorney Alvin Bragg need to convince twelve jurors beyond a reasonable doubt that Trump repeatedly falsified records to unlawfully influence the 2016 presidential election.

"This case has nothing to do with your personal politics or your feelings about a particular political issue," prosecutor Joshua Steinglass told prospective jurors on Thursday. "It's not a referendum on the Trump presidency, a popularity contest, or any indication of who you plan to vote for this fall. This case is about whether this man broke the law."

Trump's lawyers are expected to focus their efforts on going after the credibility of prosecution witnesses, suggesting the case itself is politically motivated and arguing that the former president never intended to commit a crime.
