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.

As the prospective alternates continue to answer the questionnaire questions one by one, some jurors have revealed loose connections to Trump and others surrounding the case.

A young woman who works in financial services said that her father is a "lifelong friend" of Chris Christie, the former New Jersey governor who then ran Trump's 2016 transition team before becoming a critic of the former president.

The mention of Christie's name drew a rare laugh from Trump.

The woman also revealed a loose connection to Trump's former attorney Michael Cohen.

A man who lives in Midtown and said he uses his spare time to "try to find a wife" said he has multiple family members who work for the New York State Court -- and is related to a court officer who's currently present in the courtroom. Trump attorney Todd Blanche let out a laugh.

The man said it wouldn't affect his ability to be fair and impartial.

One woman stood up and tearfully explained she served time in Massachusetts over 10 years ago. Trump appeared to crane his neck and turn all the way to look at her, before Judge Merchan called her to the bench for a sidebar.

"I apologize for crying," the woman said as she continued with her questionnaire.

Trump has been sitting at the defense table flipping through papers that contain either charts, photos or graphics.
