In the usual case, the prosecution’s office would instruct the grand jury on the charges and the law, and then the jurors would vote. The grand jury is usually made up of 23 people, and at least 16 who have heard the evidence need to be present to vote, but the decision does not have to be unanimous.

If 12 members of the grand jury vote to indict, then the prosecution would draft up an indictment and the jury foreperson would sign it. The indictment gets filed under seal with the court, so initially the public would not see it. Once the indictment is filed, the prosecution team would typically reach out to the defense attorneys to coordinate a time for the defendant to voluntarily surrender.

Despite Trump’s post on social media Saturday suggesting that he would be arrested imminently, a Trump spokesperson said that his attorneys have not been informed of any charges so far.

If the case proceeds as other high-profile cases have in the past, and if Trump turns himself in, he could be processed someplace within the district attorney’s office, according to sources familiar with the office.

That would normally include paperwork, fingerprinting, a mug shot and a cross-check of any outstanding criminal charges, which would all happen behind closed doors. Sometime soon thereafter he would be arraigned on the charge (or charges) in court in front of a judge. That would be public.

At that point, Trump or his attorney on his behalf would enter a plea, and he would then be released with another court date. Trump would not have to post bail given the nature of the charges.
