Billionaire Elon Musk announced on May 28 that he is leaving his role as a top adviser to President Donald Trump. In a statement on X, Musk thanked Trump for the opportunity to reduce "wasteful spending" as head of the Department of Government Efficiency (DOGE), a role he held since Trump's first day in office. His tenure saw thousands of federal job cuts and controversial moves like dismantling USAID and accessing sensitive data without oversight. Musk's departure follows clashes with Trump over a major spending and tax-cut bill, which Musk argues will worsen the federal deficit.
