Federal agents searched the Washington home of Representative Ilhan Omar on Monday, October 12, as part of a criminal investigation, three weeks before the midterm elections.

The Justice Department said Homeland Security Investigations agents “executed a judicially authorized search warrant.” It has said little else publicly.

The New York Times reported that the warrant listed possible immigration-related crimes, including false statements and fraudulent paperwork. Fox News, citing two sources, said the case concerns immigration paperwork filed by her late father when she was a child. An official described it as part of a multiyear investigation that includes whistleblower complaints.

Omar, a Democrat from Minnesota who came to the United States as a child refugee from Somalia, called the search “an attempt to target political enemies and weaponize federal law enforcement,” and said she would “not be silenced.” She has not been charged with a crime.

President Donald Trump said he had nothing to do with it. “I think she's a terrible person, but that's really up to the DOJ,” he said. Top Democrats criticized the timing, noting the Justice Department's long-standing practice of avoiding overt investigative steps involving candidates shortly before an election.

The same day, Trump attacked Somali and Haitian immigrants at a rally in Ohio.
