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.

In June of 2016, as the National Enquirer evaluated the merits of Karen McDougal's claim of a year-long affair with Trump, Trump's attorney Michael Cohen instructed Pecker to purchase her story -- and suggested that Trump would compensate the company for the cost, according to Pecker.

Pecker recalled from the stand a conversation he had with Cohen, in which Cohen told him, "You should go ahead and buy this story."

"So I said to him … 'Who's going to pay for it?'' Pecker testified, saying Cohen replied, "'Don't worry, I'm your friend, the boss will take care of it.'"

Pecker said he interpreted that to mean that if the National Enquirer purchased the story, Trump or the Trump Organization would reimburse him.

Picking up on his testimony from Tuesday, Pecker said that when he spoke with Trump about McDougal's story, he recalled that Trump called McDougal "a nice girl" and asked Pecker what he should do about it.

"I think you should buy this story and take it off the market," Pecker said, explaining that he "believed the story was true. I think that it would be embarrassing to himself and also to his campaign."

During her negotiations with the National Enquirer, McDougal represented that "she didn't want to be the next Monica Lewinsky," Pecker said.
