Two people familiar with the matter who were not authorized to discuss it publicly said Trump’s team had been informed that he's been indicted on seven counts and that prosecutors had contacted lawyers to advise them of the indictment shortly before Trump announced it himself on his Truth Social platform.

“This is indeed a DARK DAY for the United States of America,” Trump posted. “We are a Country in serious and rapid Decline, but together we will Make America Great Again!”

Within 20 minutes of his announcement, Trump, who said he was due in court Tuesday afternoon in Miami, had begun fundraising off it for his 2024 presidential campaign.

Prosecutors have said that Trump took roughly 300 classified documents to Mar-a-Lago after leaving the White House, including some 100 that were seized by the FBI last August in a search of the home that underscored the gravity of the Justice Department’s investigation.
