A federal investigation into Rep. Ilhan Omar’s 1990s immigration and naturalization paperwork intensified in mid-October 2026 with a court-authorized search of her Washington residence and subpoenas to relatives. Authorities are examining whether her late father listed her age incorrectly to allow derivative citizenship in 2000. President Trump and DHS officials have publicly discussed denaturalization as a goal, but no civil or criminal denaturalization case has been filed in court. Such proceedings require judicial findings of material fraud, face high evidentiary standards, and historically take years. With the 2026 resolution deadline only weeks away and Omar continuing to serve in Congress, traders assign low probability to formal deportation by year-end.
