U.S. President Donald Trump said on his social-media platform over the weekend that he is “giving serious consideration to taking away” Rosie O’Donnell’s U.S. citizenship, calling the comedian “a threat to humanity.” The remark escalates a public feud that has simmered since 2006 and resurfaced periodically during Trump’s political career. Trump’s threat came after O’Donnell criticized the administration’s handling of catastrophic floods in Texas that have left at least 120 people dead and 160 missing. O’Donnell, a Long Island-born U.S. citizen who relocated to Ireland following Trump’s 2024 re-election, responded on Instagram, labeling the president a “criminal con man” and vowing to fight any attempt to strip her of citizenship. Legal scholars note that the 14th Amendment prevents the government from revoking the citizenship of people born in the United States without their consent. Ana Navarro, co-host of ABC’s “The View,” told viewers, “This is not North Korea—no president has the authority to unilaterally take anybody’s citizenship away.” Support for O’Donnell has also come from former talk-show host Ellen DeGeneres and other public figures. While the White House has not detailed a legal basis for the threat, the episode underscores the president’s willingness to target individual critics and revives a nearly two-decade-old personal rivalry that continues to play out in public.
