From an AP story by Eric Tucker, Jill Colvin, and Michael Balsamo headlined “Trump charged over classified documents in first federal indictment of an ex-president”:

Donald Trump said Thursday that he was indicted for mishandling classified documents at his Florida estate, a remarkable development that makes him the first former president in U.S. history to face criminal charges by the federal government that he once oversaw.

The indictment carries unmistakably grave legal consequences, including the possibility of prison if he’s convicted.
