Former President Trump has filed a new emergency appeal to change the venue of his criminal trial.

Oral arguments are scheduled for this afternoon to determine whether the trial should be temporarily paused.

The motion is expected to cite some of the responses prospective jurors gave during the jury selection process.

Trump's prior attempts to move the trial out of Manhattan have failed.

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.

Judge Juan Merchan is visibly irritated with the lack of evidence presented by defense attorney Todd Blanche.

"You have presented nothing," Merchan said. "I have asked eight or nine times; show me the exact post he was responding to."

"You're losing all credibility with the court," Merchan said after Blanche suggested Trump has been careful to comply with the gag order.

Blanche attempted to represent that Trump did not intend to violate the gag order, but Merchan did not appear satisfied by the response.

"Are you testifying under oath that this is his position?" Merchan asked.

"Do you want me to put him on the stand?" Blanche asked, though Trump did not take the stand.

Merchan strongly reacted earlier when Blanche suggested there were two tiers of justice in the courtroom.

"There are two systems of justice. Mr. Weisselberg is in prison, and Mr. Cohen is a witness," Blanche said, in reference to the former Trump Organization CFO who was sentenced to jail time for perjury.

"There are two systems of justice in this courtroom -- is that what you are saying?" Merchan responded.
