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.

Many of the prospective alternates having been speaking freely about their opinions of former President Trump during individual questioning by defense attorney Susan Necheles.

As the former president looked on, one man said there were many categories to Trump: "He's a family man. He's a businessman," the man said. "Clearly he has brought a lot of value to the economy."

But he said his opinion was split over Trump himself.

"I really like lower taxes in this country. I like lower regulation," the man said. "When I think about the Republican Party and why we bring religion and women's rights with their own bodies," that's where he said he splits from Trump, concluding his impression is both "neutral and positive."

Another man conceded he posted online a handful of times about Trump in 2016 and "around the time of the insurrection." Asked for his impression of Trump, he responded, "I'd say it's fairly negative."

"You continue to hold that opinion of a strong dislike?" Necheles asked him. "Based on his rhetoric," the man answered, though he declared himself open-minded.

"What is your opinion?" Necheles asked another prospective alternate, the management consultant who likes the outdoors.

"I think not in agreement with a lot of policies. But it's also something that I've had to take a step back and really talk to a lot of people who are close to me that he has connected with," he responded. "You need to take both sides."
