US Probes Congresswoman Ilhan Omar Over Alleged Marriage to Brother for Immigration Fraud

US federal investigators have reportedly obtained DNA evidence as part of an investigation into allegations that Democratic Congresswoman Ilhan Omar married her brother to help him obtain US immigration benefits.

The New York Post reported on October 19, 2026, citing unnamed sources, that the evidence could help prosecutors examine the longstanding allegations against the Minnesota representative. However, the reported DNA findings have not been independently confirmed publicly, and no criminal charges against Omar have been announced in connection with the allegations.

The investigation reportedly intensified following a federal search of Omar’s Washington, DC, residence on October 12. According to Reuters, investigators are examining her historical immigration and naturalisation records, while agents reportedly seized her cellphone and other materials during the search. Prosecutors have also issued subpoenas as part of the inquiry.

Omar, who arrived in the United States as a Somali refugee in 1995 and became a US citizen in 2000, has repeatedly denied wrongdoing. She has described the investigation as politically motivated, while her legal team has challenged the actions taken by federal authorities.
The allegations that Omar married her brother have circulated for years. A 2019 investigation by PolitiFact, which examined reporting by the Minneapolis Star Tribune, found that the available evidence at the time did not conclusively establish that the man in question was her brother.

Although the latest reports suggest investigators are examining DNA evidence, the specific findings and their significance have not been made public. The allegations therefore remain unproven, and any determination of criminal liability would depend on evidence established through the legal process.
