Law enforcement officials are making heightened security preparations ahead of Former President Donald Trump's first appearance in federal court on criminal charges. Federal and local authorities monitor online threats and potential gatherings of far-right extremists while increasing police presence. Trump faces a 37-count federal indictment, including allegations of willfully keeping classified documents after leaving the White House. Pro-Trump rallies, including one organized by the Proud Boys, are being monitored in Miami. This case marks the first time a former president has been indicted on federal charges, and legal experts believe the charges pose a serious legal threat with potentially severe punishments if he is found guilty. Trump's travel plans to Miami are yet to be finalized. While some of his supporters have alluded to potential violence, including war suggestions, there is no nationally coordinated response from his fragmented base.
