Department of Homeland Security Secretary Markwayne Mullin publicly alleged that Rep. Ilhan Omar married her brother to exploit the immigration system, and warned that an ongoing federal investigation could end with her deportation.
Mullin made the remarks Thursday at a GOP midterm convention in Dallas during a discussion with conservative podcaster Benny Johnson. The DHS secretary did not hedge. He told the audience the department has an active investigation into Omar's immigration history and that the probe could uncover fraud serious enough to strip her of the citizenship she obtained more than two decades ago.
Just the News reported Mullin's central claim bluntly: the Minnesota Democrat, he said, entered a fraudulent marriage to bring a relative into the country. Omar has vehemently denied the allegation, though the information provides no direct quote from her responding to Mullin's latest statements.
Mullin did not leave the accusation as political commentary. He framed it as a matter of federal law with a specific enforcement outcome.
"We know that she married her brother to try to bring him to the United States."
That was Mullin's statement to the Dallas audience, as reported by the New York Post. He went further, explaining the legal framework that could apply. Lying on an immigration application, he said, carries no statute of limitations. If DHS can prove an applicant should never have been granted entry or citizenship, deportation remains on the table, no matter how many years have passed.
Omar became a naturalized U.S. citizen in 2000, when she was seventeen years old. That was twenty-six years ago. Mullin's argument is that the clock does not matter if the underlying application was built on fraud.
He also stated that Omar's ex-husband now lives in London, though he did not name the individual. Omar legally married Ahmed Nur Said Elmi, a UK citizen, in February 2009 and dissolved the marriage in December 2017.
For all the force of Mullin's language, the public record as of now contains no formal charges, no deportation proceedings, and no official DHS written statement confirming the scope or status of the investigation. Everything reported rests on Mullin's verbal statements at a political convention.
That distinction matters. A cabinet secretary telling a partisan audience that his department "knows" a sitting member of Congress committed immigration fraud is an extraordinary claim. It is not the same as a filed indictment, a court ruling, or even a formal agency announcement with documentary evidence attached.
Mullin insisted the investigation is not politically motivated. But he made the announcement at a GOP midterm convention, not from a DHS podium, and he offered no documents or specific evidence to support his assertion. The open questions are significant: What has DHS actually gathered? Has the investigation been formally opened and documented? Under what legal authority would deportation of a naturalized citizen proceed?
Omar's financial dealings have drawn separate scrutiny in recent months. Her husband, Tim Mynett, reportedly earned just $200 last year, one year after disclosing up to $30 million in assets, a gap that has raised its own set of questions.
The claim that Omar married her brother is not new. It has circulated in conservative media and political circles for years. But Mullin's remarks represent the first time a sitting DHS secretary has publicly endorsed the allegation and tied it to an active federal investigation with deportation as a stated possible outcome.
That escalation changes the political stakes considerably. Omar is a naturalized citizen, a sitting member of Congress, and a prominent figure in the progressive wing of the Democratic Party. If DHS has real evidence of immigration fraud, the public deserves to see it. If it does not, a cabinet official just made an unsubstantiated accusation against a political opponent at a party convention.
Investigators have also pressed for answers on a dramatic swing in Omar's reported household wealth, with questions surrounding a $30 million discrepancy in her financial disclosures that remains unresolved.
Mullin's statement that there is "no expiration" on immigration fraud consequences is legally accurate in broad terms. Federal law does allow for the revocation of naturalization and subsequent deportation if citizenship was obtained through willful misrepresentation or concealment of a material fact. But proving that standard in court, against a sitting member of Congress, no less, requires more than a convention-stage declaration.
Omar has vehemently denied ever marrying her brother, though no direct quote from her responding to Mullin's September 2026 remarks appears in the available reporting. Her office's silence, or its response, if one exists, is a gap in the record that matters.
Separately, Omar has faced questions about her congressional operations. She has run her congressional office out of a Somali center she funded with donations from convicted fraudsters, adding another layer to the pattern of controversy surrounding her conduct in office.
The ball is now in DHS's court, and in Omar's. If the department has evidence that Omar lied on her immigration application, the next step is a formal legal proceeding, not another rally appearance. If Omar's denial is truthful, the investigation will bear that out. Either way, the American public is owed more than a convention soundbite from one side and silence from the other.
Her revised financial disclosures have already drawn scrutiny, with her reported net worth plummeting from millions to near zero in amended filings, a pattern that suggests the congresswoman's public accounts of her own affairs deserve continued examination.
Accountability is not a talking point. It is a process, one that requires evidence, legal proceedings, and transparency. If Mullin has the goods, the country will know soon enough. If he does not, he owes an explanation for why a cabinet secretary used a partisan stage to level one of the most serious accusations possible against a sitting member of Congress.
