Federal investigators conducted a court-authorized search of Representative Ilhan Omar’s residence in October 2026 and issued grand-jury subpoenas to family members as part of an immigration-fraud probe centered on possible misstatements about her age and her father’s background when she derived citizenship in 2000. The Justice Department has not filed charges or a denaturalization complaint, and Omar has denied any wrongdoing while describing the inquiry as intimidation. The second Trump administration has sharply increased civil denaturalization filings overall, exceeding 160 cases through September, yet legal experts note that revocation requires proving material fraud in federal court and faces significant evidentiary and procedural thresholds. These factors, combined with the absence of a formal complaint to date, shape trader assessments of the likelihood of a filing by early 2027 deadlines.
