Miami police prepare for protesters outside courthouse where Trump is being arraigned

Miami police are preparing for the possibility of thousands of protesters outside the federal courthouse where former President Donald Trump is expected to be arraigned Tuesday. 

Trump is facing 37 felony charges related to his handling of classified documents after he left the White House. Trump told Fox News last week that he will plead not guilty.

The security preparations come as Trump is expected to be booked and processed after surrendering to U.S. Marshals — and after Trump urged his supporters to converge on Miami, through a social media post on his Truth Social platform.
