Prosecutors have called former American Media Inc. executive David Pecker as their first witness.

The DA alleges that Pecker, who oversaw the National Enquirer, engaged in a conspiracy with Trump and Trump's then-attorney Michael Cohen to help influence the 2016 election by killing negative stories about Trump.

In his opening statement, defense attorney Todd Blanche sought to eviscerate Michael Cohen's credibility, saying Cohen is obsessed with Donald Trump, has a desire to see Trump incarcerated and has a propensity to lie.

"He has a goal, an obsession, with getting Trump. I submit to you he cannot be trusted," Blanche said.

On Sunday night, Cohen publicly posted online that he had a "mental excitement about this trial" and the testimony he would deliver, Blanche said.

"His entire financial livelihood depends on President Trump's destruction," Blanche said. "You cannot make a serious decision about President Trump by relying on the words of Michael Cohen."

"I have a spoiler alert," defense attorney Todd Blanche told jurors during his opening statement. "There is nothing wrong with trying to influence an election. It's called democracy."

Amid frequent objections from prosecutors, Blanche argued that the Manhattan district attorney has attempted to make the payments and non-disclosure agreements between Trump and Stormy Daniels "sinister" to the jury.

Judge Merchan had to interrupt Blanche's opening after multiple objections from prosecutors, then he met the parties at a sidebar conference, after which he struck a line from Blanche's opening.

"There is nothing illegal about entering into a non-disclosure agreement. Period," Blanche restated after the portion of his opening was struck from the record.

Blanche's opening has come off more casual and off-the-cuff than the state's opening, with Blanche improvising and posing hypotheticals to argue that accountants at the Trump Organization did not run the invoices by Trump as he was "running the country."

"'Hey, we got this invoice. I know we are trying to cover it up here,'" Blanche said sarcastically about how prosecutors described how accountants received invoices from Cohen. "Absolutely not."

According to Blanche, Trump was unaware of how the invoices were processed by his employees.

"President Trump has nothing to do -- nothing to do -- with the invoice, with the check being generated, or with the entry on the ledger," Blanche said, arguing that Trump was busy "in the White House while he was running the country."

"The reality is that President Trump is not on the hook -- criminally responsible -- for something Michael Cohen might have done years after the fact. The evidence will prove otherwise," Blanche said.

Donald Trump is "not just our former president, he's not just Donald Trump that you've seen on TV," said defense attorney Todd Blanche in his opening statement.

"He's also a man. He's a husband," Blanche said. "He's a father."

Blanche pushed back on the DA's overall allegation that the payments to Trump's attorney Michael Cohen were weren't only payback for Stormy Daniels by using the prosecutor's own words against him.

Blanche noted that Cohen paid $130,000 to Daniels, but that Trump paid back Cohen a total of $420,000. If Trump really was a frugal businessman, as prosecutors said, why would he overpay that money, Blanche asked.

"Ask yourself, would a frugal businessman, a man who pinched his pennies, repay a $130,000 debt to the tune of $420,000?" Blanche asked.

Blanche repeatedly reiterated that Cohen truly was an attorney for Trump and was doing legal work for him, pointing out that Michael Cohen's own email signature noted he was Trump's attorney.

"None of this was a crime," Blanche said, saying the 34 counts against Trump "are really just 34 pieces of paper."

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.
