Could Trump strip citizenship from Elon Musk, Zohran Mamdani or Rosie O’Donnell?
📝 Summary:
In a move drawing fierce legal scrutiny and widespread alarm, President Donald Trump has publicly suggested that several of his political critics—including Elon Musk, Zohran Mamdani, and Rosie O’Donnell—could be subject to citizenship revocation. While Trump’s remarks were not part of any official legal action, they reflect the administration’s escalating rhetoric and ongoing efforts to expand denaturalization policies as part of a broader crackdown on immigration.
During public comments and posts on Truth Social, Trump claimed he would “look into” deporting Elon Musk, a naturalized U.S. citizen originally from South Africa. He also threatened Mamdani, a New York mayoral candidate and Ugandan-born U.S. citizen, with arrest and deportation, citing unverified claims that Mamdani might be in the country illegally. On social media, Trump labeled comedian Rosie O’Donnell—a natural-born citizen—a “Threat to Humanity” and floated the idea of revoking her citizenship, despite the constitutional impossibility of doing so without voluntary renunciation or legal basis.

The statements coincide with Trump’s Justice Department ramping up denaturalization efforts. A June memo instructed civil division attorneys to prioritize denaturalization in all eligible cases, focusing on individuals tied to violent crimes, fraud, or national security threats. While historically rare—averaging just 11 cases per year between 1990 and 2017—the Trump administration has already filed five denaturalization cases since returning to office, with more expected.
Legal experts have swiftly condemned Trump’s remarks as unconstitutional and politically motivated. Only federal courts, not the president, can revoke citizenship—and only in limited cases involving fraud or illegal procurement. Immigration attorney Matthew Hoppock and Migration Policy Institute fellow Muzaffar Chishti both warned that politicizing denaturalization undermines due process and could chill free speech among immigrants and naturalized citizens.
For now, Trump’s comments appear symbolic, but they signal a broader shift in how citizenship—and dissent—are being framed in political discourse. Advocates warn that even failed attempts at denaturalization could be weaponized to suppress criticism and sow fear, especially among immigrant communities.
