Judge Juan Merchan has now seated and sworn in six jurors to sit in judgment of former President Trump, after each side used several peremptory strikes and other prospective jurors were stricken over politically-charged social media posts.

"You are the first six jurors selected for this trial," Merchan said.

Juror No. 1, the foreperson, is a man born in Ireland who works in sales and lives in West Harlem.

Juror No. 2 is an oncology nurse at Memorial Sloan Kettering who lives on the Upper East Side.

Juror No. 3 is an attorney who lives in Chelsea.

Juror No. 4 is an IT consultant who lives on the Lower East Side and is originally from Puerto Rico.

Juror No. 5 is a charter school teacher from Harlem.

Juror No. 6 is a software employee who works for Disney and lives in Chelsea.

Three jurors from the first batch of 96 prospects have been selected for the jury.

After the defense raised a series of motions to remove jurors for cause, citing their social media posts, Judge Juan Merchan formally approved three jurors:

- an Irish-born salesman;

- an oncology nurse; and

- an attorney who lives in Manhattan's Chelsea neighborhood.

The selections came after Judge Merchan blocked one other motion from the defense to strike a juror for cause and granted another.

The juror Merchan agreed to remove was an Upper West Side bookseller who recently re-posted an AI video to social media mocking Trump, which included a fake Trump saying, "I'm dumb as f---."

"I thought it would be funny," the juror said.

The government then used three of its ten peremptory strikes and the defense used four.

After declining to strike a potential juror for her Facebook content, Judge Merchan granted a defense motion to strike another juror for a social media post.

"Good news!!" the post read. "Trump lost his court battle on his unlawful travel ban!!!"

If the post ended there, Judge Merchan said, he would allow him to remain in contention. But the post didn't stop there.

"Get him out and lock him up," the post continued.

Those post shows the prospective juror expressing "the desire that Trump be locked up," Merchan said. "Everyone knows that if Mr. Trump" is found guilty, he could face prison time.

"I don't think I can allow this juror to remain," the judge said, before agreeing to strike the juror.

Judge Merchan declined to strike for cause the prospective juror who posted what the defense called "hostile" Facebook videos, explaining that he believed the juror when she told the court that she would follow the facts of the case.

"I don't want a juror on this panel who lies to us. I don't want a juror on this panel who misleads us," he said. "And for this reason, I did want to hear from the juror."

Ultimately, Merchan found her assurances to be honest.

"I was able to see her demeanor, I was able to hear her voice," he said. "That juror looked me right in the eye, and when she said she could be fair and impartial, she meant it."

"I find her to be credible," Merchan concluded, before denying the defense motion to remove her from the jury.

David Pecker, who once called Donald Trump "a personal friend of mine," flashed a big smile as he took the stand as the trial's first witness, belying the gravity of the moment.

Pecker cackled loudly into the microphone, jolting the room, when prosecutor Josh Steinglass, asked him about his various phone numbers that he struggled to remember.

Pecker, 72, was the publisher of the National Enquirer but prosecutors said he was "acting as a co-conspirator" in helping buy and bury damaging stories about Trump, including a doorman's false claim that Trump had fathered a love child and a Playboy model's claim of a sexual relationship with Trump, who has denied both allegations.

Trump, who once said Pecker would make a "brilliant" choice as editor of Time magazine, listened while leaning forward in his chair, arms crossed on the table, an unhappy look on his face.

Pecker testified that he had final say whether to publish any story involving a famous person.

"I had the final say of the celebrity side of the magazine," Pecker said. "We used checkbook journalism. We paid for stories."

Pecker is testifying pursuant to a subpoena. He has also secured a non-prosecution agreement with the Manhattan district attorney's office.
