Before entering the courtroom for today's proceedings, former President Donald Trump spoke to reporters, repeating his claims that Judge Juan Merchan is a "highly conflicted judge" overseeing a "rigged trial."

Trump also expressed his annoyance about the ongoing cold conditions in the courtroom, on a day where it's a brisk 50 degrees in lower Manhattan.

"So we have another day of court in a freezing courthouse, it's very cold in there," he said. "On purpose, I believe. They don't seem to be able to get the temperature up. It shouldn't be that complicated. But we have a freezing courthouse, and that's fine."

Defense attorney Emil Bove is scheduled to continue his cross-examination of former National Enquirer publisher David Pecker this morning, on Day 8 of former President Donald Trump's hush money trial.

On Thursday, under direct examination, Pecker detailed his publication's "catch-and-kill" deal with Trump, explaining how his publication paid Playboy model Karen McDougal $150,000 for the exclusive rights to her story about an alleged year-long relationship she had with Trump, then kept it under wraps so it wouldn't "embarrass Mr. Trump or embarrass or hurt the campaign."

Under cross-examination from Bove, Pecker testified that there was "nothing wrong" with those kind of arrangements, and that they were "standard operating procedure" for publications like his, listing several politicians -- including Rep. Rahm Emanuel and Arnold Schwarzenegger -- for whom he had caught and killed stories.

Former President Trump, exiting the courtroom at the end of Day 7 of his trial, called the day's court proceedings "breathtaking."

He specifically remarked on the Supreme Court's hearing this morning on his bid for presidential immunity in his federal election interference case, which Trump was forced to miss due to his criminal trial.

"I heard the meeting was quite amazing. The justices were on their game," Trump said.

Prosecutor Joshua Steinglass alleged that defense attorney Emil Bove used a "totally improper line of questioning" during Bove's cross-examination of former National Enquirer publisher David Pecker.

Judge Juan Mechan, addressing Bove, at one point raised his voice slightly, saying, "Are you missing my point? Because I don't think you are responding to what I am saying."

Merchan said that the jurors will be corrected about the alleged misimpression at the start of court tomorrow.

The judge then adjourned the day's proceedings, with court scheduled to resume at 9:30 a.m. ET Friday.

Trump attorney Todd Blanche sought to "test" jury candidates on their assurances that his client would "get a fair shake" as he began his questioning of the first group of prospective jurors.

"This isn't a baseball game," Blanche said, referring to a sports reference Assistant District Attorney Josh Steinglass had made during his questioning of jurors. "This is extraordinarily serious."

Blanche pressed jurors on their opinion of Trump, asking each of them whether they harbored any views about him in any capacity -- political or otherwise.

"If we were sitting in a bar, I'd be able to tell you," said the bookseller from the Upper West Side. But in the courtroom, he continued, that opinion has "absolutely no bearing on the case."

"I walk in here, and he's a defendant," he said. "That's all he is."

When another juror indicated that her awareness of Trump comes in part through the lens of her gender -- "I'm a female," she said -- Blanche asked her to elaborate.

"I know that there have been opinions on how he doesn't treat females correctly, stuff like that," she said. "I honestly don't know the story. So I don't have a view on it."

Another juror, an older male, drew laughter from courtroom when he said Trump "makes things interesting."

"I find him fascinating. He walks into a room, and he sets people off," the juror said. "I find that really interesting."

"Um, all right," Blanche said. "Thank you."
