Former President Trump has arrived at the courthouse in lower Manhattan.

He stepped out of his motorcade, waved, and walked into the side entrance.

A small group of supporters and protesters both cheered and booed his arrival.

Former President Trump is en route to the courthouse in lower Manhattan for this morning's proceedings.

The former president left for the the courthouse from Trump Tower in Midtown Manhattan.

Court this morning may start with a hearing over what prosecutors can ask Trump during cross-examination should he take the stand later in the trial.

The judge would hear arguments from both the people and the defense. The proceedings would then move into jury selection later in the morning.

Prosecutors have indicated they would want to cross-examine Trump on approximately "thirteen different court determinations," including the recent civil finding that he sexually abused columnist E. Jean Carroll, the criminal conviction of the Trump Organization last year, the finding that he committed a decade of business fraud, and the dissolution of his charity, according to sources familiar with the matter.

The hearing -- known as a Sandoval hearing -- is standard practice before jury selection and typically occurs when a defendant signals a willingness to testify.

In a filing last month, Trump's lawyers requested a Sandoval hearing to limit the scope of Trump's potential cross examination, if he opted to testify.

Former President Trump will leave his Trump Tower apartment in Midtown Manhattan this morning and travel down to lower Manhattan for the first day of jury selection in his criminal hush money trial.

The proceedings come after Trump unsuccessfully tried three times last week to delay the start of the trial through the filing of appeals.

As a defendant in a criminal case, the former president will be required to be in court for the entire trial, which is expected to take six to eight weeks.

After a prospective alternate said he has a minority stake in a company that produces Michael Cohen's "Mea Culpa" podcast, Trump leaned forward and turned toward the man at the mention of his former attorney's name.

The man also said he had volunteered for a Democratic get-out-the-vote effort during Hillary Clinton's 2016 campaign.

Several of the prospective alternates said they had read Trump's "Art of the Deal," including a management consultant who likes to be outdoors when he's not working.

A retired teacher made the requisite pledges, saying, "I will solely make my decision solely based on the evidence in the courtroom. There is no reason why I can't be a fair and impartial juror."

"I believe that everyone should obey the law," he said.

A woman with an MBA in information systems who likes to "cook, bake, watch hockey" inquired about the court's schedule for Passover. Told the court was planning to break early this coming Monday and Tuesday, she said that would give her plenty of time to travel to her seders in New Jersey.

A contract specialist for a fintech company said she likes to take her two boys to Knicks games and Rubik's Cube speed competitions.

Another prospective alternate skipped the questionnaire and told the judge she could not be impartial.

"After thinking about this yesterday after hearing the questions, I don't think I can be impartial," the woman said before Judge Merchan excused her without objection.
