"It was election fraud, pure and simple," prosecutor Matthew Colangelo told the jury during opening statements as he outlined the hush payment to adult film actress Stormy Daniels and how it was logged by the Trump Organization

Dylan Howard, then editor of the National Enquirer, had called Trump attorney Michael Cohen to inform him about Daniels and the story that she had of a sexual liaison with Trump, which the former president has long denied.

"Cohen then discussed the situation with Trump who is adamant that he did not want the story to come out," Colangelo said. "it could have been devastating to his campaign."

At the time, Trump and the campaign were "deeply concerned" about the "Access Hollywood" video, the prosecutor said. Cohen wired the $130,000 to Daniels' lawyer to keep her quiet.

"Cohen made that payment at Donald Trump's direction and for his benefit and he did it with the special goal of influencing the election
This was not spin or communications strategy. This was a planned, coordinated long-running conspiracy to influence the 2016 election to help DT get elected through illegal expenditures to silence people who had something bad about his behavior. It was election fraud, pure and simple," Colangelo said.

Prosecutor Matthew Colangelo read aloud part of the transcript of the infamous "Access Hollywood" tape to jurors.

"You can do anything," Colangelo slowly read to the jurors, quoting Trump from the tape. "Grab them by the p----. You can do anything."

According to Colangelo, the October 2016 release of the tape had an "immediate and explosive" impact on Donald Trump's presidential campaign.

"Seeing and hearing a candidate in his own words, in his own voice, with his own body language ... has a much greater impact on voters than words on paper," Colangelo said. "The campaign went on immediate damage control mode to blunt the impact of the tape."

The campaign was concerned about the impact it might have on Trump voters or even the possibility that Trump could lose the Republican nomination one month out from the election, according to Colangelo.

"The Republican National Committee even considered whether it was too late to replace their own nominee," Colangelo said.

Former President Trump, sitting at the defense table, softly shook his head "no" when prosecutor Matthew Colangelo told the jurors that Trump formed a "conspiracy" with Michael Cohen and David Pecker to "help him get elected."

It was one of the most notable reactions from Trump as he sits and listens to prosecutors lay out their story of the case.

Colangelo then brought up the "Access Hollywood" tape and said it showed Trump "bragging about sexual assault," Trump shook his head no again, pursing his lips. He did not react when Colangelo, quoting Trump on the tape, said, "grab them by the p----."

Earlier, as Colangelo brought up a former Trump doorman who was he said was paid off as part of the alleged catch-and-kill scheme, Trump -- looking annoyed -- leaned over and tapped his lawyer Todd Blanche. When Colangelo said the doorman was paid $30,000 to bury his story, Trump raised his eyebrows and grabbed onto a pen.

The former president has been passing notes and sliding papers between Blanche and attorney Emil Bove, and leaning side-to-side, whispering to them. Blanche at one point pulled out his own sticky note and slid a note back to Trump.

At other times he has hardly seemed engaged at all, slumping in his red leather chair looking straight forward with no facial expression, or fidgeting with his head tilting back and forth. At one point during jury instructions he let out a yawn.

"It starts with that August 2015 meeting in Trump Tower," prosecutor Matthew Colangelo told jurors about the alleged conspiracy, in his opening statement.

Following a meeting between Donald Trump, his then-lawyer Michael Cohen, and AMI executive David Pecker, the three engaged in a three-prong conspiracy to help influence the 2016 election, according to Colangelo.

First, the National Enquirer would run "headline after headline that extolled the defendant's virtues," according to Colangelo.

"Pecker had the ultimate say over publication decisions," Colangelo said, adding that Trump edited, killed, and suggested the cover of the magazine.

Second, the National Enquirer would run negative stories attacking Trump's opponents in the 2016 Republican primary, such as attacks on Ben Carson or Marco Rubio.

Third, the "core of the conspiracy" was killing negative stories about Trump -- evolving into the catch-and kill scheme, Colangelo said.

"The National Enquirer ran these stories as part of the conspiracy launched after the Trump Tower meeting," he said.

Former National Enquirer publisher David Pecker, back on the witness stand, pointed at Donald Trump and flashed a smile when he was asked to identify the defendant. Trump turned his chin up and grinned at his longtime friend.

"I met Mr. Trump at Mar-a-Lago," Pecker said. "I've had a great relationship with Mr. Trump over the years."

That relationship started in 1989 when Pecker wanted to start a magazine called Trump Style.

"He was very helpful in introducing me to other executives in New York. He would always advise me of parties or events that I would go to," Pecker said, adding that Trump was among the first to congratulate him upon acquiring the National Enquirer.

Pecker described how Trump became a "major celebrity" after launching The Apprentice and later Celebrity Apprentice, and how the National Enquirer was there to juice Trump's profile.

"He was always kind enough to send me the content showing the ratings and I was able to publish that," Pecker said of their "great mutual beneficially relationship.

Pecker said he considered Trump a friend from 2015 to 2017, calling him by the familiar "Donald," as he pursued the White House for the first time.

"After he announced his run for the presidency I saw Mr. Trump more frequently, maybe once a month," Pecker said. The two spoke "maybe once every couple of weeks."

Pecker recalled meeting Trump in his office when his assistant brought a batch of invoices and checks to sign.

"As I recollect the entire package was stapled together," Pecker said.

"So you observed him reviewing an invoice and signing a check?" prosecutor Josh Steinglass asked. "That's correct," Pecker responded.

"I would describe him as very knowledgeable, very detail-oriented, almost as a micromanager," Pecker said.

When Steinglass asked how Trump was with money, Pecker responded, "He was very cautious and very frugal."
