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.

With six seats filled on the jury that will determine the outcome of Donald Trump's first criminal trial, a new group of 96 New Yorkers was ushered into the courtroom and sworn in as prospective jurors.

Many of them craned their necks to get a look at the defendant.

"Ma'am, ma'am, put your cellphone away," a court security officer told one woman who tried to pull out her phone after spotting Trump.

One man and woman were seen whispering feverishly to one another.

After members of the group were sworn in, Judge Merchan told them he was sending them home for the day.

"I know that you've been sitting around all day, waiting for something to happen, and I want you to know that that wasn't lost on us," Merchan said, telling them the proceedings would start right away when they return Thursday morning following Wednesday's day off.

Before the new panel was brought in, the judge asked Trump's defense team to confirm that the social media posts it's been digging up are all are public. Trump attorney Todd Blanche confirmed they were.
