Joseph R. Biden Jr. wrapped up his presidency on Monday with a tone far from the optimism he’s known for. After nearly 50 years in public service, the outgoing president left Washington with a warning: the fight for democracy isn’t over. “We’re not leaving the fight,” Biden told supporters and staff as he prepared to depart. His farewell came just moments before his successor, Donald J. Trump, was sworn in. In his final hours, Biden made a series of high-profile pardons, including five family members and key figures like General Mark A. Milley, Dr. Anthony Fauci, and former Representative Liz Cheney. Biden described the pardons as necessary, citing “exceptional circumstances” and fears of ongoing political attacks. “I cannot in good conscience do nothing,” he said. This wasn’t the ending Biden likely envisioned when he launched his 2020 campaign, driven by a desire to counter Trump’s divisive rhetoric. His narrow victory marked a turning point, but the tension between the two leaders persisted. Now, as Trump returns to power, Biden’s actions suggest he’s bracing for potential retaliation against his family and allies. The scene at Joint Base Andrews, where Biden bid farewell, was a stark contrast to the hopeful tone of his inauguration four years ago. Instead of celebrating achievements, the outgoing president left with a somber message about the challenges ahead. As the political chapter between Biden and Trump closes, the question remains: what comes next? For now, Biden’s final acts as president reflect a man determined to protect those closest to him, even as he steps away from the spotlight. ---
