Homeland Security Secretary Markwayne Mullin says federal investigators are probing whether Rep. Ilhan Omar married her own brother to get him into the country, an allegation that could carry deportation consequences.
Mullin made the claim during an interview with conservative commentator Benny Johnson at the Republican National Convention in Dallas. He described the inquiry as an "ongoing investigation" into Omar's family immigration history and said it extends beyond the marriage allegation itself.
Times of India reported that Mullin did not present documentary evidence during the interview and did not identify any specific charges being considered against Omar, the Minnesota Democrat who has represented the state's 5th Congressional District since 2019. But the DHS secretary spoke in definitive terms about the central allegation.
Mullin told Johnson that DHS has enough confidence in the allegation to state it plainly:
"We know that she married her brother to try to bring him into the United States."
He framed the investigation as a straightforward enforcement matter, not a partisan exercise. Mullin said authorities would move forward only if the evidence warranted it:
"If we actually move a case forward, it's not a political case. It's an actual case because they did things wrong."
An unnamed DHS spokesperson, responding to an inquiry from Newsweek, declined to confirm the specific allegations or discuss investigative techniques. But the spokesperson offered a pointed statement of principle: "No one, including members of Congress, are above the law."
The allegation centers on Omar's 2009 marriage to Ahmed Nur Said Elmi, a British citizen. Conservative critics and community members have long alleged that Elmi is Omar's biological brother and that the marriage was arranged to help him enter the United States. Omar has repeatedly denied that Elmi is her brother and has rejected claims she committed immigration fraud, calling the accusations false and politically motivated.
Omar married Elmi in February 2009. The New York Post reported that the marriage was not dissolved until December 2017. No direct verbatim quotes from Omar responding to Mullin's latest statements appeared in any of the reporting.
Mullin went further than previous officials by raising the possibility of deportation. He told Johnson that lying on an immigration application carries no statute of limitations, meaning potential violations could be pursued years or even decades after they allegedly occurred.
Just The News reported Mullin's warning in direct terms:
"If you lied about certain things about your application. There's no expiration to that. If we can prove it, that you shouldn't have been here in the first place, we'll deport you."
Marriage fraud is a federal crime punishable by up to five years in prison and a $250,000 fine. If investigators determined that false information was provided during the immigration process, the consequences could extend well beyond criminal penalties to include revocation of citizenship or lawful status.
Mullin also suggested the investigation may reach beyond Omar herself, indicating that her family's broader entry into the United States is under scrutiny. He did not specify what additional illegal activity investigators might be examining.
The claims about Omar and Elmi are not new. They gained national attention in 2019, when then-President Donald Trump and conservative groups called for an investigation. Trump told a crowd in May that he believes Omar "married her brother, which is totally illegal."
Two major news organizations examined the allegations during that earlier wave of scrutiny. The Star Tribune reviewed records and communications related to Omar's marriages and reported discrepancies involving the timeline of her marriages and divorces, but did not establish that Elmi was her brother. The New York Times examined the claims as well and reported that while questions had been raised about Omar's personal history, no publicly available evidence demonstrated that Elmi was her sibling.
That gap between allegation and proof has defined the story for years. Mullin's interview marks the first time a sitting cabinet secretary has publicly claimed the allegation as established fact, using the words "we know" rather than hedging with "we believe" or "we suspect." Whether DHS possesses evidence that previous investigations did not uncover remains an open question, Mullin offered no documents, no witness names, and no case number.
Federal authorities have also been tight-lipped about the investigation's scope. ICE has withheld records related to the probe, citing active enforcement proceedings, a move that suggests the inquiry has advanced beyond a preliminary review but tells the public nothing about what investigators have found.
The DHS investigation is not the only federal attention Omar has drawn. She has claimed that a federal agent was stationed outside one of her Minnesota town halls, adding to a pattern of friction between the congresswoman and federal law enforcement.
Back in her district, a retired state trooper has launched a fraud-focused campaign to unseat her in Minnesota's 5th District, making the immigration allegations a centerpiece of his challenge. The political and legal pressures are converging at the same time.
Omar's denials have been consistent over the years. She has called the brother-marriage allegation false and described it as a smear rooted in anti-immigrant and anti-Muslim bias. But consistent denials are not the same as a rebuttal backed by records, and Omar has not, in any of the available reporting, produced documents that conclusively disprove the claim. Neither side has laid its cards on the table.
Mullin's public statements shift the dynamic. A cabinet secretary does not typically announce the existence of an ongoing investigation into a sitting member of Congress on camera unless the department is prepared to follow through. If DHS has the goods, Omar faces consequences that go far beyond political embarrassment. If it does not, the department will have made an extraordinary public accusation against an elected official without the evidence to back it up.
Either way, the American public deserves to see the evidence, or the admission that it does not exist. Accountability means showing your work, not just making the claim.
