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.

With Donald Trump following along from the defense table, head cocked slightly to the side, David Pecker described the negotiations conducted with Karen McDougal to purchase the exclusive rights to her story about an alleged year-long relationship with Trump.

Pecker said that Trump's attorney Michael Cohen authorized negotiations to begin, then during those negotiations, "Michael was very agitated," constantly asking "Why is this taking so long?"

"To purchase the lifetime rights to Karen McDougal was going to cost $150,000. Plus Karen wanted to restart her career. She wanted to write for the celebrity magazines. She wanted to be on the cover of the life and fitness titles. She had a major problem when her breast implants were removed and she wanted to write about that," Pecker testified.

Pecker said he asked Cohen, "Who is going to reimburse me for this?" He said Cohen responded "Don't worry about it, I'm your friend the boss will take care of it.'"

When prosecutor Josh Steinglass asked Pecker who "the boss" was, Pecker answered "The boss would have been Donald Trump"

Prosecutors then displayed for the jury the contract with McDougal, dated August 5, 2016. It awarded AMI, the Enquirer's parent company, the rights to her story of a relationship she had "with any then-married man." Pecker said "she was referring to Donald Trump."

Pecker testified he needed to "validate" the amount of money AMI was going to pay, so the contract included other provisions, like having McDougal write monthly columns on aging and fitness.

"With respect to campaign laws, I wanted to have the contract be a record that stipulates the services she was going to perform for American Media had a basis for it, the $150,000," Pecker said.

"Was it your primary purpose to buy the life rights?" Steinglass asked. "Yes it was," Pecker responded.

"Were the other provisions to disguise the true nature of this contract?" Steinglass asked. "Yes," Pecker replied, letting out a sigh.

In June of 2016, as the National Enquirer evaluated the merits of Karen McDougal's claim of a year-long affair with Trump, Trump's attorney Michael Cohen instructed Pecker to purchase her story -- and suggested that Trump would compensate the company for the cost, according to Pecker.

Pecker recalled from the stand a conversation he had with Cohen, in which Cohen told him, "You should go ahead and buy this story."

"So I said to him … 'Who's going to pay for it?'' Pecker testified, saying Cohen replied, "'Don't worry, I'm your friend, the boss will take care of it.'"

Pecker said he interpreted that to mean that if the National Enquirer purchased the story, Trump or the Trump Organization would reimburse him.

Picking up on his testimony from Tuesday, Pecker said that when he spoke with Trump about McDougal's story, he recalled that Trump called McDougal "a nice girl" and asked Pecker what he should do about it.

"I think you should buy this story and take it off the market," Pecker said, explaining that he "believed the story was true. I think that it would be embarrassing to himself and also to his campaign."

During her negotiations with the National Enquirer, McDougal represented that "she didn't want to be the next Monica Lewinsky," Pecker said.

Former National Enquirer publisher David Pecker has resumed his testimony.

The veteran tabloid executive is fielding questions from prosecutors about how his publication handled its initial interactions with Karen McDougal, who approached the National Enquirer with allegations that she had had a year-long sexual relationship with Donald Trump.

When one of his reporters met with McDougal, the reporter found that her allegations "could be true, but she didn't have any corroborating evidence," Pecker said.
