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.

"Karen McDougal was a Playboy model," former National Enquirer publisher David Pecker said, recalling how he learned in June 2016 "that there's a Playboy model who is trying to sell a story about a relationship that she had with Donald Trump for a year."

Pecker said he immediately called Trump's then-attorney Michael Cohen to inform him. By then, he was speaking to Cohen "a couple times a week," but that soon changed. Pecker said he and Cohen spoke "much more frequently" about McDougal's claims.

"Michael was very agitated. It looked like he was getting a lot of pressure to get the answer right away," Pecker said. "He kept on calling, and each time he called he seemed more anxious."

Pecker said he assumed "Mr. Trump was asking Michael Cohen, 'Did we hear anything yet?'" Pecker said.

"Did you ever come to believe that Michael Cohen had spoken with Mr. Trump about McDougal's claims?" prosecutor Josh Steinglass asked.

"Yes I did," Pecker responded before recounting a phone conversation Pecker said he himself had with Trump.

"I said I think the story should be purchased and we should buy it," Pecker recalled telling Trump. "Mr. Trump said to me, 'I don't buy stories. Anytime you do anything like this, it always gets out.'"

Ultimately, McDougal was paid $150,000 and promised a series of exercise articles in the publication.

Following that testimony, court was adjourned.

It's expected the jury will hear more on McDougal upon Pecker's return to the witness stand, when court resumes on Thursday.
