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.

Former National Enquirer publisher David Pecker described one of the most heated moments so far during the catch-and-kill arrangement between him, Donald Trump and Trump's then-attorney Michael Cohen.

When Cohen approached Pecker with a plan to reimburse the National Enquirer for buying the exclusive rights to Karen McDougal's story, the two men drew up paperwork in which Cohen would repay the Enquirer's parent company, AMI, through a shell company he created, Pecker said.

But Pecker testified that he had a change of heart after consulting with his general counsel.

"I called Michael Cohen and I said to him that the agreement we signed -- the deal was off. I am not going forward, it is a bad idea," Pecker testified. "I want you to rip up the agreement."

"He was very, very, angry. Very upset, screaming basically at me. And I said, I'm not going forward with this agreement, rip it up," Pecker said.

Pecker said Michael Cohen then brought up "the boss."

"And Michael Cohen said, the boss is going to be very angry with you. And I said, I'm sorry, I am not going forward. The deal is off," Pecker recounted. "And he said, I can't believe it. I'm a lawyer, I'm your friend. I don't understand why you're not going forward. I said I am not going forward. Period."

Pecker previously described at length that he was aware that the National Enquirer's payment to Karen McDougal in order to catch and kill her story for the benefit of Trump's campaign would amount to an illegal campaign contribution -- softening his tone when he testified to this.
