Federal investigators launched a probe into Rep. Ilhan Omar’s 2000 naturalization, executing a search warrant at her Washington-area home on October 12, 2026, and issuing grand-jury subpoenas to relatives. The inquiry centers on possible misstatements about her age when her father naturalized, which could have affected derivative citizenship eligibility, along with separate questions about his military history. DHS has referred a substantial file to the DOJ, yet no civil denaturalization complaint under 8 U.S.C. § 1451 has been filed as of November 10. Any such action would require proving willful misrepresentation by clear and convincing evidence in federal court, a high bar that historically limits these cases. Traders are watching for indictment decisions or a formal petition that could trigger market resolution.
