A man apparently set himself on fire outside the courthouse while Trump was inside during the trial.

The person was badly burned and taken away from the scene on a stretcher.

It was not immediately clear if the incident was related to the criminal proceedings.

The hearing on the scope of former President Trump's potential testimony is scheduled to take place today at 3:15 p.m. ET

Known as a Sandoval hearing, it will determine the extent of the prosecution's cross-examination.

Prosecutors have indicated they would like to question Trump about matters beyond the criminal case, including his recent $454 million civil fraud judgment, the two verdicts in the E. Jean Carroll cases and a lawsuit he filed against Hillary Clinton that resulted in legal sanctions.

The six alternate jurors have been sworn in, raising their hands.

"We have now completed jury selection for this case," Judge Merchan said.

The alternate jurors are five women and one man.

Alternate Juror No. 6 lives on the Upper East Side and is a project manager for a construction company and a mother of three children who "does whatever my kids want me to do in my spare time."

Her father was convicted of a federal crime when she was in high school. She said she was "shielded" from the details at the time.

"We have a full panel," Judge Merchan said after alternate jurors 5 and 6 were selected.

Alternate Juror No. 5 is originally from Texas and has spent four years in New York.

She works in creative operations for a clothing company and ejoys concerts, restaurants and music.

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.
