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 testified on cross-examination that the publication's limited involvement in Stormy Daniels' hush money payment was unrelated to the August 2015 Trump Tower meeting where Pecker vowed to serve as the "eyes and ears" of Trump's presidential campaign.

Pecker's testimony on cross-examination about the Daniels story appeared consistent with his testimony yesterday about his strong desire not to be involved in the Stormy Daniels payment.

Pecker said yesterday that he did not want to be involved in the story due to concerns about reputational harm to the National Enquirer and a lack of reimbursement for the other payments he had made to suppress previous Trump stories.

"I said, we already paid $30,000 to the doorman, we paid $150,000 to Karen McDougal, and I am not a bank. I am not paying out any further disbursements among us," Pecker testified yesterday. Pecker said he instructed National Enquirer Chief Content Officer Dylan Howard to flag the Stormy Daniels story to Michael Cohen, who made the payment to Daniels himself.

Asked about Daniels' payment on cross-examination, Pecker said that the National Enquirer's limited involvement was unrelated to their vow to Trump.

"You did not consider the Stormy Daniels story to be part of any agreement you had in August 2015?" defense attorney Emil Bove asked.

"That is correct," Pecker said.

"You wanted nothing to do with it?" Bove said.

"That's correct," Pecker said.

Pecker added that he did not "authorize" Howard to continue communicating with Stormy Daniels' lawyer Keith Davidson about the payment.

When Howard raised concerns to Pecker that Davidson had not yet been paid by Michael Cohen, Pecker said he was angry that Howard continued to communicate with Davidson about the story. In addition to the nature of the story -- which Pecker said could endanger the National Enquirer's relationship with its distributors -- Pecker said Cohen's delay in paying Daniels' lawyer could result in reputational harm to the National Enquirer.

"Frankly, you were not happy to be hearing that?" Bove asked about Cohen's delayed payment.

"Yes," Pecker said.

"The main concern was Howard's reputation?" Bove asked.

"Yes," Pecker said.
