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.

Donald Trump's lawyer Todd Blanche, during the contempt hearing on the limited gag order in the case, defended the former president's comments by arguing that Trump was responding to political attacks.

"President Trump does in fact know what the gag order allows him to do and not allow him to do," Blanche said. "There is no dispute that President Trump is facing a barrage of political attacks from all sides."

According to Blanche, while the limited gag order prohibits statements about a witness' potential participation in a case, Trump is allowed to make comments in response to political attacks from potential witnesses like Michael Cohen and Stormy Daniels.

"They are talking about their very strong dislike of President Trump," Blanche said about a post related to former Daniels attorney Michael Avenatti's comments on Michael Cohen.

Judge Juan Merchan questioned Blanche about what exactly made Trump's response "political" in nature.

"You believe that everything Mr. Avenatti said does not relate to the trial, but the use of the word 'pardon' makes it political and in a sense authorizes your client to respond?" Merchan asked.

"It's everything. It can't just be a single word," Blanche responded.

"When your client is violating the gag, I expect more than one word," Merchan said.

Conroy asked Merchan to advise Trump that for future violations of the gag order, "incarceration is an option should it be necessary."
