Donald Trump has been indicted on charges of 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 Justice Department was expected to make public a seven-count indictment ahead of a historic court appearance next week in the midst of a 2024 presidential campaign punctuated by criminal prosecutions in multiple states. The indictment carries unmistakably grave legal consequences, including the possibility of prison if Trump's convicted. But it also has enormous political implications, potentially upending a Republican presidential primary that Trump had been dominating and testing anew the willingness of GOP voters and party leaders to stick with a now twice-indicted candidate who could face still more charges. And it sets the stage for a sensational trial centered on claims that a man once entrusted to safeguard the nation's most closely guarded secrets willfully, and illegally, hoarded sensitive national security information.
