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.

Following the loss of Juror. No. 2, attorneys are now discussing an issue with yet another juror -- Juror No. 4 -- after Assistant District Attorney Joshua Steinglass said the the DA's team did research that "possibly called into question the veracity" of the answers he gave on the jury questionnaire.

Steinglass said a person with the same name as Juror No. 4 -- the Puerto Rican man who said he found Trump "fascinating and mysterious" -- had been arrested in the 1990s in Westchester for "tearing down political advertisements."

“I actually believe the propaganda that was being ripped down was political posters that were on the right -- the political right," Steinglass said.

He suggested that Juror No. 4's answer to question 19 on the questionnaire -- if you have ever been accused or convicted of committing a crime -- then "was not accurate."

Steinglass added they discovered the juror's wife had been embroiled in a "corruption inquiry" that resulted in her "entering in a differed prosecution agreement ... with the Manhattan DA's office."

Steinglass said they felt they were "ethically and legally obligated to bring this information to the court."

Judge Merchan said he instructed Juror No. 4 to be in court at 9:15, but he still has not shown up.

Trump attorney Todd Blanche said he did not consent to dismissing the juror without first hearing from him. They will revisit the issue later.
