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.

Court resumed after the lunch break with the individual questioning of 18 prospective jurors, who are seated in the jury box.

Assistant District Attorney Josh Steinglass began with a rhetorical question for the group: "How am I considered for this case of all cases?"

Steinglass said the case was not a referendum on the Trump presidency or anyone's politics. "This case is about whether this man broke the law," he said, gesturing toward Trump.

"I could be objective," one of the prospective jurors, the security officer with Rangers seats and a flip phone, said.

Before the questions resumed, Judge Juan Merchan addressed the temperature in the courtroom.

"I want to apologize that it's chilly in here," Merchan said.

Earlier, when defense attorney Todd Blanche asked to make the courtroom warmer, the judge had said he feared a one-degree bump in the nearly century-old building could increase the temperature by 30 degrees.
