Ilhan Omar Federal Investigation: HSI Search, Seized Passport and What Denaturalization Really Means

Federal investigators have opened a new and serious chapter in the long-running questions surrounding Rep. Ilhan Omar’s immigration history.
On October 12, 2026, federal agents executed a judicially authorized search of Omar’s Washington, D.C.-area residence. The operation was carried out by Homeland Security Investigations (HSI), the principal investigative arm of the Department of Homeland Security.

According to reporting by Fox News, the New York Post, and The Associated Press, agents seized a cellphone, personal computers, notebooks, and a physical passport under a sealed criminal warrant. Several outlets also reported that investigators obtained a DNA sample. The Department of Justice has acknowledged the existence of a court-approved search as part of an ongoing investigation but has not released the full warrant.
The investigation is reportedly focused on historical immigration paperwork. Omar, who was born in Somalia, came to the United States as a refugee in 1995 and became a naturalized U.S. citizen in 2000 when she was a minor, deriving citizenship through her father, Nur Omar Mohamed.

At issue is whether there were knowing and material false statements in those early filings. Federal documents described by commentator Glenn Beck and cited by other media reportedly reference 18 U.S.C. §1542, which covers false statements in a passport application, and mention civil denaturalization as a potential remedy being examined.

Former federal immigration judge Nathan Hansen, who was briefly appointed earlier this year, told Fox News Digital that the bar for such a case is extremely high. A criminal conviction does not automatically lead to loss of citizenship, Hansen said, and denaturalization would require a separate civil proceeding brought by the Department of Justice with clear and convincing evidence that citizenship was procured through fraud.
Sources tell Fox and the Post that a federal grand jury in Minnesota has issued subpoenas to relatives as part of the document-driven probe. No charges have been filed against Omar as of October 28, 2026.
Omar, 43, who represents Minnesota’s 5th District and is one of the first Somali-American members of Congress, has denied any wrongdoing. In a statement through her office, she described the investigation as politically motivated. Her legal team has filed a motion challenging the search and seeking return of seized property, arguing that the materials are protected by legislative privilege.

The White House has weighed in. President Donald Trump said on October 22 that Omar used a “fake name” to be sworn in, referencing a federal filing that identified her as “Ilhan Nur Said Elmi, a/k/a Ilhan Abdullahi Omar,” and called for her resignation. The filing itself does not constitute a finding of fraud.

Legal experts caution that this is a long process. Denaturalization cases live at the narrow intersection of biography, paperwork, and exacting law, and the government must prove that a false statement directly led to the grant of citizenship. If charges are ever filed, they would be handled in federal court, followed potentially by a separate civil case.

For now, the investigation remains active, with agents reviewing seized devices and documents. Omar continues to serve in Congress while the legal process unfolds
