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.

"I have a spoiler alert," defense attorney Todd Blanche told jurors during his opening statement. "There is nothing wrong with trying to influence an election. It's called democracy."

Amid frequent objections from prosecutors, Blanche argued that the Manhattan district attorney has attempted to make the payments and non-disclosure agreements between Trump and Stormy Daniels "sinister" to the jury.

Judge Merchan had to interrupt Blanche's opening after multiple objections from prosecutors, then he met the parties at a sidebar conference, after which he struck a line from Blanche's opening.

"There is nothing illegal about entering into a non-disclosure agreement. Period," Blanche restated after the portion of his opening was struck from the record.

Blanche's opening has come off more casual and off-the-cuff than the state's opening, with Blanche improvising and posing hypotheticals to argue that accountants at the Trump Organization did not run the invoices by Trump as he was "running the country."

"'Hey, we got this invoice. I know we are trying to cover it up here,'" Blanche said sarcastically about how prosecutors described how accountants received invoices from Cohen. "Absolutely not."

According to Blanche, Trump was unaware of how the invoices were processed by his employees.

"President Trump has nothing to do -- nothing to do -- with the invoice, with the check being generated, or with the entry on the ledger," Blanche said, arguing that Trump was busy "in the White House while he was running the country."

"The reality is that President Trump is not on the hook -- criminally responsible -- for something Michael Cohen might have done years after the fact. The evidence will prove otherwise," Blanche said.
