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."

Asked to share her responses to the jury questionnaire, one prospective alternate said she wanted to "jump ahead" to Question 34, which asks whether any strong opinions of Trump would interfere with the ability to be fair.

"The last day, after some introspection, I don't think I can be impartial," the woman said. "I had every intention when I first started, but I think after the questions posed to prospective jurors and asking the questions to myself, I don't think I can be impartial."

Judge Merchan excused her without objection from the attorneys.

A prospective alternate who works for the New York City Law Department said in response to a question that she had read Trump's "Art of the Deal." Trump, who appeared to have his eyes closed, opened them right away at that response and looked at the woman.

The woman also said she had been sexually assaulted "a couple of times on the train."

Trump also appeared to have been chewing on something. He has been conferring with defense attorney Emil Bove throughout the more mundane parts of the questionnaire responses.

A chef for a "large hospitality group" said he follows the White House account on Instagram, "so when Mr. Trump was president, obviously I was receiving updates." Trump turned his head to look at the man after he had been slumped over the defense table looking down.
