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.

After court resumed for the afternoon session, David Pecker retook the stand.

The former National Enquirer publisher testified that six months after Donald Trump became president, Trump hosted a "thank-you dinner" for Pecker and some of his business associates.

After taking photos in the Oval Office -- "Jared Kushner was there, Sean Spicer was there" Pecker said -- Trump asked Pecker to walk with him along the colonnade "past the Rose Garden," Pecker recalled. The jury saw a photo of the two men on that walk.

Trump said that on that walk, Trump asked Pecker, "How's Karen doing?" referring to Karen McDougal, who the National Enquirer had paid to catch-and-kill her story claiming a year-long relationship with Trump.

"She's doing well. She's quiet. All's going good," Pecker recalled responding.

Eight months later, in March 2018, Pecker said Trump called him about a television interview McDougal had conducted.

"He said 'Did you see the Anderson Cooper interview with Karen McDougal?' I said yes. He said, 'I thought we had an agreement with Karen that she can't give any interviews or be on any television shows.' So I said yes we have an agreement, but I amended it," said Pecker, who testified earlier that he had done so following the election.

Pecker testified that Trump was very upset. "He couldn't understand why," Pecker said. "He couldn't believe that I did it."

Pecker said Trump also called him after Stormy Daniels appeared on a television interview a short while later.

"He said, 'We have an agreement with Stormy Daniels that she cannot mention my name or do anything like this, and each time she breaches the agreement it's $1 million penalty,'" Pecker said.
