The first witness prosecutors with the Manhattan DA's office plan to call is former National Enquirer publisher David Pecker, according to two sources familiar with the matter.

ABC News previously reported that prosecutors planned to call Pecker as a witness, but sources now say he's expected to be the first witness to take the stand.

Pecker served as the longtime chief executive of American Media Inc., which published the National Enquirer.

Shortly after Trump announced his 2016 presidential campaign, Pecker met with Trump and agreed to act as the "eyes and ears" of the campaign by looking out for and killing negative stories about Trump, according to the Manhattan DA.

As part of the arrangement, Pecker allegedly directed a deal to pay $30,000 to a former Trump Tower doorman regarding the false allegation that Trump allegedly fathered a child out of wedlock, prosecutors say. Then-Trump attorney Michael Cohen allegedly insisted that the deal stay in place even after AMI discovered the allegation was false, and AMI paid the doorman, according to the Manhattan DA.

After a week-long selection process, the jurors in Donald Trump's New York hush money case are scheduled to hear opening statements this morning in the first criminal trial of a former U.S. president.

To prove their case, lawyers for Manhattan District Attorney Alvin Bragg need to convince twelve jurors beyond a reasonable doubt that Trump repeatedly falsified records to unlawfully influence the 2016 presidential election.

"This case has nothing to do with your personal politics or your feelings about a particular political issue," prosecutor Joshua Steinglass told prospective jurors on Thursday. "It's not a referendum on the Trump presidency, a popularity contest, or any indication of who you plan to vote for this fall. This case is about whether this man broke the law."

Trump's lawyers are expected to focus their efforts on going after the credibility of prosecution witnesses, suggesting the case itself is politically motivated and arguing that the former president never intended to commit a crime.

Former President Donald Trump reiterated his plans to testify in his criminal trial as he exited the courtroom at the end of the day.

"We just had another hearing and the trial starts on Monday, which is long before a lot of people thought," Trump said. "The judge wants to go as fast as possible."

The former president again, without evidence, called the trial a witch hunt orchestrated by his political rivals.

Judge Juan Merchan declined to order prosecutors to disclose their first witness after defense attorneys remade a request from yesterday.

"I still think that under the circumstances, the people's response is understandable, and I am not going to compel them to do anything," Merchan said, citing the hearing set for Tuesday to hold Trump in contempt for violating the judge's limited gag order.

Yesterday, prosecutors expressed concern that Trump might attack the initial witnesses if he learned their names. Today, prosecutor Joshua Steinglass offered a compromise -- that they would turn over the first witnesses name on Sunday with a strict condition.

"If that should be tweeted, that will be the last time we extend that courtesy," Steinglass said.

Steinglass said that while the testimony of the first witness will likely begin on Monday, it is unlikely the witness finishes their direct examination by the end of the day.

Court was subsequently recessed for the day.
