The Trump administration’s ongoing federal investigation into Rep. Ilhan Omar’s 2000 naturalization centers on alleged age misrepresentation in her father’s citizenship application and possible concealment of his military service, with a Homeland Security Investigations raid on her Washington-area home on October 12, 2026, and grand-jury subpoenas to family members. Officials have described the probe as aimed at building evidence for denaturalization and potential deportation under civil proceedings that require clear and convincing proof of material fraud or willful misrepresentation. The Justice Department has accelerated denaturalization filings in 2026, yet legal experts note high evidentiary hurdles, expired criminal statutes of limitations on some claims, and the need for court action before any citizenship revocation. Omar has denied wrongdoing and characterized the effort as politically motivated. No complaint has been filed as of late October, though border officials have publicly referenced a “strong case” if evidence supports it.
