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.

When the National Enquirer's parent company AMI signed a non-prosecution agreement with federal prosecutors in New York in September 2018, AMI was negotiating to sell the Enquirer and two other tabloids to Hudson News Group for $100 million, former publisher David Pecker testified under cross-examination.

Defense attorney Emil Bove suggested the pending sale put Pecker under pressure to resolve a federal campaign finance investigation over its payment to quash stories damaging to Donald Trump's presidential ambitions.

"You knew to finalize that deal, to consummate it, you had to clear out the investigations?" Bove asked.

"Yes," Pecker responded. "From a timing standpoint it would have added stress to the transaction."

On Thursday Pecker testified he had been "very worried" about the investigation. He had received a letter from the Federal Election Commission and said he called up Michael Cohen. "I said 'I'm very worried,'" he testified.

Pecker said Cohen responded, "Why are you worried? Jeff Sessions is the Attorney General and Donald Trump has him in his pocket."

The defense appears to be suggesting AMI cooperated with federal campaign finance investigations not because the company had done anything wrong related to the 2016 Trump campaign, but out of financial considerations in order to preserve the $100 million deal with Hudson News, which was finalized in April 2019.
