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.

Asked to share her responses to the jury questionnaire, one prospective alternate said she wanted to "jump ahead" to Question 34, which asks whether any strong opinions of Trump would interfere with the ability to be fair.

"The last day, after some introspection, I don't think I can be impartial," the woman said. "I had every intention when I first started, but I think after the questions posed to prospective jurors and asking the questions to myself, I don't think I can be impartial."

Judge Merchan excused her without objection from the attorneys.

A prospective alternate who works for the New York City Law Department said in response to a question that she had read Trump's "Art of the Deal." Trump, who appeared to have his eyes closed, opened them right away at that response and looked at the woman.

The woman also said she had been sexually assaulted "a couple of times on the train."

Trump also appeared to have been chewing on something. He has been conferring with defense attorney Emil Bove throughout the more mundane parts of the questionnaire responses.

A chef for a "large hospitality group" said he follows the White House account on Instagram, "so when Mr. Trump was president, obviously I was receiving updates." Trump turned his head to look at the man after he had been slumped over the defense table looking down.
