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.

Trump attorney Todd Blanche sought to "test" jury candidates on their assurances that his client would "get a fair shake" as he began his questioning of the first group of prospective jurors.

"This isn't a baseball game," Blanche said, referring to a sports reference Assistant District Attorney Josh Steinglass had made during his questioning of jurors. "This is extraordinarily serious."

Blanche pressed jurors on their opinion of Trump, asking each of them whether they harbored any views about him in any capacity -- political or otherwise.

"If we were sitting in a bar, I'd be able to tell you," said the bookseller from the Upper West Side. But in the courtroom, he continued, that opinion has "absolutely no bearing on the case."

"I walk in here, and he's a defendant," he said. "That's all he is."

When another juror indicated that her awareness of Trump comes in part through the lens of her gender -- "I'm a female," she said -- Blanche asked her to elaborate.

"I know that there have been opinions on how he doesn't treat females correctly, stuff like that," she said. "I honestly don't know the story. So I don't have a view on it."

Another juror, an older male, drew laughter from courtroom when he said Trump "makes things interesting."

"I find him fascinating. He walks into a room, and he sets people off," the juror said. "I find that really interesting."

"Um, all right," Blanche said. "Thank you."
