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.

In his cross-examination of David Pecker, the former National Enquirer publisher who ran the publication's parent company, AMI, defense lawyer Emil Bove sought to draw a contrast between AMI's conduct with Donald Trump and its work with another celebrity-turned-politician: Arnold Schwarzenegger.

Earlier today, Pecker testified about an agreement with Schwarzenegger ahead of the actor's run for California governor. According to Pecker, Schwarzenegger agreed to serve as an editor-at-large for some of AMI's fitness magazines in exchange for help quashing negative stories about Schwarzenegger's past interactions with women.

"A number of women called up the National Enquirer about stories that they have to sell on different relationships or contacts and sexual harassment they felt that Arnold Schwarzenegger did," Pecker said. "The agreement I had with Arnold was I would call him and advise him of any stories that were out there."

Pecker described that his arrangement with Schwarzenegger -- which he said resulted in an "embarrassing" investigation into AMI's conduct -- provided him with some foundational experience when he began identifying and killing stories for Trump.

"That's how I became sensitive on this topic," Pecker.

Pressed on cross-examination about the arrangement with Schwarzenegger, Pecker acknowledged that AMI spent its own money to kill stories about the former California governor.

"It was hundreds of thousands of dollars," Pecker said.

"And Mr. Schwarzenegger never paid you back for that?" Bove asked.

"No, he didn't," Pecker said.

Pecker also testified about an effort to compel Tiger Woods to do an interview with AMI's fitness magazines by purchasing a negative story about him as leverage.

Former National Enquirer publisher David Pecker testified that he believed Donald Trump had knowledge about the $150,000 contract to buy Karen McDougal's silence regarding an alleged year-long affair.

"Do you know if anyone else besides Michael Cohen had any knowledge of this contract?" prosecutor Joshua Steinglass asked.

"Yes, I believe Donald Trump did," Pecker responded.

"Was your principal purpose to suppress the story to prevent it from influencing the election?" Steinglass asked.

"Yes," Pecker said.

"Were you aware that expenditures by corporations made for the purpose of influencing an election made in coordination with or at the request of a candidate or campaign were unlawful?" Steinglass asked.

Pecker said he was aware and confirmed that the Enquirer's parent company, AMI, never reported the payment to the Federal Election Commission.

"We purchased the story so it wouldn't be published by any other organization," Pecker said.

"Why did you not want it to be published by any other organization?" Steinglass asked.

"We didn't want the story to embarrass Mr. Trump or embarrass or hurt the campaign," Pecker said.

"Who is we?" Steinglass followed up.

"Myself and Michael Cohen," Pecker said.

According to Pecker, AMI agreed to the $150,000 payment on the promise that Donald Trump or the Trump Organization would reimburse AMI for the payment. He frequently followed up with Cohen about the reimbursement and got a similar answer from Cohen.

"Why are you worried? I am your friend. The boss will take care of it," Pecker said about Cohen's response.
