Though the precise range of charges and defendants is not clear, Trump is widely expected to be at the center of the criminal case, which could include sprawling racketeering allegations.

Fulton County District Attorney Fani Willis’ investigation has been years in the making. She empaneled a “special grand jury” in early 2022 — a quirk of Georgia law that permits prosecutors to pursue complex, focused investigations that don’t fit within the bounds of the traditional grand jury process. Though that panel spent months hauling in some of Trump’s top aides and allies, it had no power to issue indictments. Willis had to take the evidence it amassed and present it to a traditional grand jury in order to secure criminal charges.

An indictment of Trump would be the fourth criminal case against him since March. He faces charges in Manhattan for allegedly falsifying business records to cover up an affair with a porn star; federal charges in Florida from special counsel Jack Smith for hoarding classified military secrets at his Mar-a-Lago estate; and federal charges in Washington, D.C., also from Smith’s team, for his election scheme.
