(Bloomberg) -- The indictment brought by Special Counsel Jack Smith against Donald Trump marks the culmination of a two-year effort to figure out what government documents went with the former president when he left the White House — and whether any crimes were committed.

Filed under seal in federal court in Miami, the indictment was announced by Trump in a post on his Truth Social platform Thursday evening and confirmed by people familiar with the matter.

The unprecedented FBI search of Trump’s Mar-a-Lago home on Aug. 8, 2022, came after National Archives officials spent months trying to claw back records still in his possession. Trump’s lawyers and the US Justice Department then wrangled in court over whether prosecutors could use the seized materials at all. A federal appeals court ended the fight in December, siding with the government.

Trump’s campaign filing in November signaling a third White House run prompted Attorney General Merrick Garland to appoint Smith as special counsel that month. As Smith settled in, the first half of 2023 saw a procession of grand jury witnesses, sealed subpoena fights and shakeups on Trump’s legal defense team.
