Federal agents searched Rep. Ilhan Omar’s Washington, D.C., home on Monday morning under a court-approved warrant, the Justice Department said, in a move the Minnesota Democrat described as politically motivated. The department said Homeland Security Investigations agents carried out the search as part of an ongoing federal investigation. Current and former federal officials familiar with the matter said the multi-year probe includes whistleblower complaints and concerns about alleged immigration fraud. No findings establishing wrongdoing were reported. Omar, a U.S. citizen who came to the United States as a refugee from Somalia, denied the accusations and said on social media that President Donald Trump had spent years targeting her with smear campaigns. She vowed not to be silenced. Trump has said he is not involved in the investigation. Vice President JD Vance has previously accused Omar of immigration fraud, which she denies. Sharon Jackson, a 79-year-old neighbor, said she was awakened at about 4:30 a.m. by loud knocking. She told NPR she saw vans and agents wearing gloves moving to and from the congresswoman’s home. The search took place as the Trump administration faces questions about the use of federal resources and its treatment of political opponents. Separately, nearly $22 million in taxpayer funds had gone toward advertisements promoting Trump since the campaign began in late September, according to an NPR analysis of AdImpact data. Almost $10 million was spent after Trump said Oct. 5 that his super PAC would pay for the campaign. A federal judge had ordered the ads taken down, while the White House described them as public service announcements. A lawsuit filed by Common Cause and others argues the ads were funded without congressional approval, in violation of restrictions on taxpayer-funded publicity and propaganda. The search of Omar’s home and the dispute over the ads raise distinct questions, but both have intensified scrutiny of how government power and public money are used during a closely watched midterm campaign.
