Trump's attorney entered a plea of not guilty.
Former President Donald Trump made his first appearance Tuesday in a federal courtroom in Miami after he was indicted in an investigation into his handling of classified documents.
Trump, who has repeatedly denied any allegations of impropriety, entered a not guilty plea through his attorneys and did not speak at all during the court appearance.
Trump has been charged with 37 counts: 31 counts of willful retention of national defense information; one count of conspiracy to obstruct justice; one count of withholding a document or record; one count of corruptly concealing a document or record; one count of concealing a document in a federal investigation; one count of scheme to conceal; and one count of false statements and representations.
Supporters and opponents of former President Donald Trump have congregated outside the courthouse with signs and costumes to make their voices heard.
As former President Donald Trump motorcades to the courthouse, he is riding in his car alone, sources told ABC News.
Trump's lawyers, Todd Blanche and Chris Kise, are in the car behind him. Trump aide Walt Nauta, who is also charged in the federal indictment, is also riding in that car with his attorney, Stanley Woodward.
