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.

Alternate Juror No. 3 is an audio professional who offered to assist Judge Merchan with a microphone that kept cutting out. He expressed his opinion that "Donald Trump is a man, just like I am."

He said growth results from correcting their prior wrongful actions. "Every man should respond to their wrongdoings if found," he said. "If there is evidence found against a man, there should be consequences."

Alternate Juror No. 4 is a woman who said "I have no really strong opinions about President Trump."

She is married with two boys that she likes to take to Knicks games and Rubik's Cube speed competitions. She has been a contract specialist for 20 years, currently employed at a publicly traded fintech company.

The woman who participated in the Women's March and said Trump enabled homophobic and racist comments was excused. The judge called it "the safer course."
