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.

Defense attorney Todd Blanche finished questioning the first group of potential jurors, including asking them to think about their social media usage and whether it affects their opinion of Trump.

Blanche asked a man born in Mexico who became a U.S. citizen when Trump was president if that would color his jury experience.

"I think the media and the opinions of my Facebook friends are inconsequential to this trial," the man said. "Feelings are not facts."

A woman who had said she had been living in a WiFi-free lake house for much of February and March said she didn't know much about the case, but she knew about Trump's policies. She said she had "very little agreement policy-wise" with Trump, but told Blanche she "didn't sleep last night" because she was thinking so hard about fairness and impartiality.

"You want your client to have a fair shake. I will do my level-headed best to make sure that happens," she said.

This part of the day clearly interested Trump. He turned his body in the direction of the jury box, shifting his gaze from his lawyer to the people who may sit in judgment of him.

Judge Juan Merchan subsequently recessed the court for a lunch break.
