Day 4 of Trump New York hush money trial

A man lit himself on fire outside the courthouse where the Trump trial is underway, New York City Police Department officials said.

NYPD Chief of Department Jeffrey B. Maddrey said the man walked into the center of Collect Pond Park, which is directly across from the courthouse. He opened his backpack and took out pamphlets that he scattered in the park before setting himself on fire.

A CNN team on the ground observed one of the flyers. It said "NYU is a mob front" and had various allegations of wrongdoings against the school.

NYPD Chief of Detectives Joseph Kenny said police have not determined if the incident was related to Trump’s trial. He said the man did post about the incident on social media and that his internet presence will be part of the ongoing investigation.

At least one person used a fire extinguisher to try to put out the blaze, and an EMT rushed up to the man and tried to render aid, according to CNN's Laura Coates, who narrated the scene unfolding in front of her outside the courthouse.

The five remaining alternate jurors were sworn in Friday, meaning the full jury panel has now been seated in the hush money trial against Donald Trump.

There are 12 jurors and six alternates who will hear the case against the former president.

Opening statements are expected to start Monday.

Here’s a recap:

The judge said there will be a Sandoval hearing after the lunch break around 3:15 p.m. ET. That routine hearing will address Trump’s criminal history and assess how much prosecutors can ask if a defendant testifies.

The court is adjourned for lunch.

The judge is expected to hold a Sandoval hearing at 3:15 p.m. ET. This is a common preliminary proceeding that will be used to review Donald Trump’s criminal history and assess how much prosecutors can ask if he testifies.

Judge Juan Merchan tells the jurors, "I expect we're going to begin the trial on Monday."

Merchan is giving the jurors instructions not to discuss the case with others or research it.

"There are 18 jurors in total," and we cannot start until all are present each day, Merchan says.

Jurors are being called up to be sworn in now.

The last five alternates sworn in include four women and one man.

A sixth alternate juror has been selected. That means the full panel — 12 jurors and six alternates — has now been seated.

"We have our full panel," the judge said.

One more alternate juror has been added to the jury. We're up to five alternate jurors now.

Alternate No. 5 said she is married, works for a clothing company and gets her news from Google.

The potential alternate juror was dismissed after a review of his social accounts.

When referencing a quote in which he called Donald Trump "egomaniacal," he said, "it's not too far off base" from what he felt at the time.

He also said the top image of the Facebook account is his, but then suggests the posts in question are not his.

Prosecutors withdrew their opposition to the Trump team's challenge for cause.
