After attorneys for each side introduced themselves, Judge Juan Merchan said that before jury selection can begin "there are a couple of loose ends we need to go over before we start."

The first item, Merchan said, was a pair of motions filed by Trump's legal team seeking his recusal from the case, citing his past comments in interviews and his daughter's work with a Democrat-affiliated firm.

The motions, Merchan said, cite "pages and pages of screen grabs, articles, social media posts and the like" that amount only to "a series of inferences, innuendos, and unsupported speculation."

To call them "attenuated is an understatement," Merchan said.

Merchan denied the motion and said the court would not address the matter further.

"All rise," the bailiff announced at 9:59 a.m. ET. "This is the People of the State of New York v. Donald J. Trump."

And with that, proceedings are underway.

Members of the prosecution and the defense, including the former president, stood briefly as Judge Juan Merchan entered the courtroom and took his seat on the bench.

Manhattan District Attorney Alvin Bragg entered the courtroom shortly before court went into session.

Former President Trump arrived at the courtroom at 9:32 a.m. flanked by members of his legal team.

In brief remarks to reporters on the way in, he called his criminal trial an "assault on America."

"Nothing like this has ever happened before," Trump said, marking his first comments of the day as he becomes the first former American president to face criminal charges.

"There is no case," he said. "This is political persecution."

Trump also attacked President Joe Biden and said the case should not go forward.

Upon entering the courtroom, he sat at the defendant's table as his lawyers and court officers buzzed around him.

Several members of the Manhattan district attorney’s office have arrived in the courtroom.

Proceedings are scheduled to begin at 9:30 a.m. ET.

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."
