Ilhan Omar investigation is real, but can the US actually strip her citizenship?

Federal agents searched Rep. Ilhan Omar's Washington home on Monday and seized her cellphone, notebooks, personal computers, and passport. Homeland Security Investigations also issued subpoenas to some of her relatives, according to reporting on the probe. The investigation, as described by the Wall Street Journal, is aimed at building a basis to strip the Minnesota Democrat of her U.S. citizenship and deport her.

The questions under examination include how Omar obtained citizenship in 2000 after arriving from Somalia, an allegation of a sham marriage to her biological brother to gain residency, and her financial disclosures to Congress. President Trump said in January that the Justice Department is investigating Omar over discrepancies in her financial records. Vice President JD Vance said the department is also probing the marriage allegation. Omar has denied the sham marriage claim; it remains an allegation, not an established fact.

A former federal prosecutor said investigators face a "very high bar" to build a case. Denaturalization has a history: more than 22,000 Americans lost their citizenship between 1907 and 1967 based on political affiliations, race, and gender.

Former Georgia GOP Rep. Marjorie Taylor Greene said the administration is "pretending" to prepare to deport Omar — a Republican former colleague describing the effort as performance. That assessment sits alongside the concrete facts: a sitting member of Congress is under federal criminal investigation, her home was searched, and her passport is in government hands.

What is established: the search happened, the passport was seized, and the investigation is underway. What is not established: that the administration can strip Omar's citizenship or deport her.
