Donald Trump has pleaded not guilty to criminal charges alleging he retained classified documents after he left the White House.
It is alleged that US government secrets were stored in a shower, bathroom, ballroom and bedroom of his Mar-a-Lago estate.
After leaving the court, the former president stopped at a well-known Cuban cafe in Miami to greet supporters.
Mr. Trump will speak later today from his golf club in New Jersey.
Supporters of the former president have been protesting the indictment outside the Miami court.
Trump, who is campaigning to win back the White House, says the indictment is “election interference”.
Special Counsel Jack Smith, the lead investigator, says he wants a speedy trial, and that Trump is innocent until proven guilty.
