Former National Enquirer publisher David Pecker retook his seat on the witness stand after lunch, and the jury appeared engaged when prosecutor Josh Steinglass asked Pecker to explain things directly to them. Pecker slightly turned to face the jury when answering.

After the defense, during cross-examination, tried to suggest Pecker didn't want to get involved in the Stormy Daniels story for business and reputational reasons, Steinglass asked him to clarify.

"I said to Michael Cohen that after paying for the doorman story and the Karen McDougal story I wasn't going to pay anything further and I wasn't a bank," Pecker testified. "I told (editor) Dylan Howard there is no possible way that I would buy the story for $120,000 and that I didn't want anything to do with a porn star."

Steinglass asked Pecker, "Why did you reach out to Michael Cohen" about Daniels' claim of a sexual liaison with Trump?

"Based on our original agreement, any stories regarding Mr. Trump that could be embarrassing, I would call Michael Cohen right away," Pecker said.

"You weren't going to print it? You weren't going to pay for it?" Steinglass asked.

"Correct," Pecker responded.

"But you were still going to fulfill your obligation to tell Michael Cohen about it? So the campaign could squash it?" asked Steinglass.

"Yes," Pecker responded.

As he has previously, former President Trump complained on social media this morning that his supporters were being kept from gathering outside the courthouse -- even though that's not the case.

"Security is that of Fort Knox, all so that MAGA will not be able to attend this trial," Trump posted before he entered the courtroom.

But a small group of his supporters demonstrated this morning undisturbed in the designated protest area in the park outside the courthouse, where they've gathered each day of the trial this week.

Former National Enquirer publisher David Pecker, during his redirect examination, reiterated the basic terms of his catch-and-kill arrangement with Donald Trump and Michael Cohen, though he acknowledged he did not use the words "catch-and-kill" during his August 2015 meeting at Trump Tower.

"Did you specifically use the word catch-and-kill during that meeting?" prosecutor Joshua Steinglass asked.

"No, I did not," Pecker said.

"What was your understanding of the part of the agreement that involved money?" Steinglass asked.

"It was my understanding that I would use the company's sources to hear any information that was coming out on Mr. Trump or the campaign related specifically to women who would be selling their stories," Pecker said, referencing a similar arrangement with then-gubernatorial candidate Arnold Schwarzenegger.

"My understanding is [for] those stories that come up, I would speak to Michael Cohen and tell him that these are the stories that are going to be for sale. If we don't buy them someone else will, and that Michael Cohen would buy them or make sure they don't ever get published. That was my understanding from that meeting," Pecker said.

Pecker reiterated that he did not plan to publish the Karen McDougal story -- despite its value to the National Enquirer if it were true -- in order to help the Trump campaign.

"That would kind of be like National Enquirer gold?" Steinglass asked.

"Yes," Pecker responded.

"Zero intention of publishing that story?" Steinglass asked.

"That is correct," Pecker said.

"You killed the story because it helped the candidate Donald Trump?" Steinglass asked.

"Yes," Pecker said.

The proceedings subsequently broke for lunch, with redirect to resume afterward.

On redirect examination, prosecutor Joshua Steinglass sought to dismantle defense attorney Emil Bove's claim that former National Enquirer publisher David Pecker's actions on behalf of Donald Trump were nothing more than "standard operating procedure" in the tabloid industry.

Steinglass cited Pecker's previous testimony that nondisclosure agreements were commonplace in the course of his work.

But, Steinglass asked, "On how many others did the CEO -- meaning you -- coordinate with a presidential candidate for the benefit of their campaign?"

"That was the only one," Pecker said.

Referring to Michael Cohen's input on AMI's negotiation with Karen McDougal, Steinglass asked, "Is it standard operating procedure ... to have a presidential candidate's campaign person weighing in on what terms of a contract are to be amended?"

"No," Pecker replied.

Steinglass ticked through several other matters related to Pecker's arrangement with Trump, including whether it was common practice to offer a political candidate the opportunity to "accept or reject" stories, or for the paper to "run attacks" on their opponents.

Each time, Pecker answered "No" -- that they were not common practice.

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.
