MIAMI (AP) – Donald Trump became the first former president to face a judge on federal charges as he pleaded not guilty in a Miami courtroom Tuesday to dozens of felony counts that he hoarded classified documents and refused government demands to give them back. The history-making arraignment, centering on charges that Trump mishandled government secrets that as commander-in-chief he was entrusted to protect, kick-starts a legal process that will unfold at the height of the 2024 presidential campaign and carry profound consequences not only for his political future but also for his own personal liberty. Trump approached his arraignment with characteristic bravado, posting social media broadsides against the prosecution from inside his motorcade and insisting as he has through years of legal woes that he has done nothing wrong and was being persecuted for political purposes. But he sat scowling inside the courtroom with his arms crossed as a lawyer entered a not guilty plea on his behalf in a brief arraignment that ended without him having to surrender his passport or otherwise restrict his travel. But the gravity of the moment was unmistakable as he answered to 37 felony counts that accuse him of willfully retaining classified records that prosecutors say could have jeopardized national security if exposed, and the trying to hide them from investigators who demanded them back.
