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.

The prospective alternate who said her father was a friend of Chris Christie's broke down crying during the individual questioning of prospective jurors, telling assistant DA Susan Hoffinger, "This is so much more stressful than I thought it would be."

Hoffinger was quizzing potential alternates about their views of the burden of proof that prosecutors are required to meet.

"I have to be honest, I feel so nervous and anxious right now," the woman said, breaking into tears. "I'm sorry, I thought I could do this. I wouldn't want someone who feels this way to judge my case."

Judge Merchan called her up to the bench for a private conversation and excused her from the pool.

When the questioning resumed, another prospective alternate turned the tables on Hoffinger. "May I ask you a question?" he said. "The burden of proof is subjective to each individual juror?"

Hoffinger explained that "there is only one burden of proof" and that prosecutors are obligated to prove Trump's guilt beyond a reasonable doubt.

The man said he accepted that, and that he would not hold prosecutors to an even higher standard because Trump is a former president.
