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.

Prosecutor Matthew Colangelo told the jury, during his opening statement, "During this trial you're going to hear a lot about Michael Cohen.”

Trump's former personal attorney, Cohen is a key witness -- perhaps the only one that will testify to Donald Trump’s intent when he agreed to pay Stormy Daniels hush money.

The defense “will go to great lengths” to convince the jury Cohen is not credible, Colangelo said.

He acknowledged that Cohen had earlier lied regarding the matter. “He lied about it to protect his boss,” Colangelo said. “You will also learn that Michael Cohen has a criminal record.”

Colangelo told jurors they can believe Cohen despite his past mistakes.

“Cohen's testimony will be backed up by testimony from other witnesses you will hear from, including David Pecker, Keith Davidson. It will be backed up by an extensive paper trail. And it will be backed up by Donald Trump’s own words,” the prosecutor said.

Colangelo concluded by saying, “This case is about a criminal conspiracy and a cover-up, an illegal conspiracy to undermine the integrity of a presidential election and then the steps that Donald Trump took to conceal that election fraud. At the end of the case we are confident you will have no reasonable doubt that Donald Trump is guilty of falsifying business records.”
