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.

Donald Trump kept contact information for two women who alleged they had sexual relationships with him, his longtime executive assistant testified Friday as the trial's second witness.

After former National Enquirer publisher David Pecker concluded his historic testimony as the first witness in the first criminal trial of a former president, Graff, entered the courtroom with a cane. Trump turned to see her as she entered, but the two did not appear to make eye contact.

Graff's testimony appeared to be a pick-me-up for jurors, who had been listening to the same voice on the witness stand for the better part of four days.

Graff worked for the Trump Organization for 34 years, beginning in October 1987, and testified that she was responsible for keeping Trump's contacts and calendars. Graff said those contacts included Karen McDougal and Stormy Daniels

Graff testified that she created the contact entry for Karen McDougal that included two addresses, a cell phone number, and an email address.

Under questioning from prosecutor Susan Hoffinger, Graff testified she had also entered a contact for Stormy Daniels.

"It contains her mobile phone number," Graff said. "I have a vague recollection of seeing her in the reception area on the 26th floor."

Graff said she also knew Daniels was a porn star.
