The Department of Homeland Security (DHS) is actively investigating allegations that Rep. Ilhan Omar, a Democratic member of Congress from Minnesota, committed immigration fraud by marrying her brother. Senior officials have confirmed that the probe is underway, and the outcome could have significant legal consequences if authorities determine that Omar misrepresented herself during the U.S. citizenship process.

The investigation centers on longstanding claims that Omar entered into a marriage with her brother in order to facilitate his entry into the United States. If substantiated, such actions could potentially lead to denaturalization—the revocation of her U.S. citizenship—and even deportation. These are rare but serious outcomes in cases where immigration fraud is proven.
Border Czar Tom Homan, a former acting director of Immigration and Customs Enforcement (ICE), confirmed the existence of the investigation during an appearance on Fox News’ “The Sunday Briefing.” Homan declined to discuss specifics of ongoing criminal investigations but emphasized the impartiality of the process. “No one is above the law,” Homan stated, reiterating that Homeland Security Investigations (HSI) would continue its work regardless of the subject’s public profile.
DHS Officials Address Allegations
At the Republican National Committee’s Midterm Convention last week, Secretary of Homeland Security Markwayne Mullin made public remarks referencing Rep. Omar. Mullin stated, “Something’s going to happen,” and alleged, “We know that she married her brother to bring him into the United States; we know he lives now in London.” Mullin suggested that the investigation could extend beyond Omar herself, potentially encompassing broader issues of family migration and possible illegal activity related to entry into the United States.
Mullin further commented on the potential consequences, saying, “If we can prove it, that you shouldn’t have been here in the first place, we’ll deport you.” His remarks highlight the seriousness with which DHS is treating the allegations and the possible implications for Omar’s immigration status if wrongdoing is established.
Denaturalization Process Explained
Rep. Omar is a naturalized U.S. citizen, having obtained citizenship after immigrating to the United States. Homan explained that denaturalization is a significant and complex process. If an individual is found to have lied or misrepresented material facts in order to obtain citizenship, the government has the authority to revoke that status. “We’ve done it before many times over the last 40 years that I’ve been around,” Homan said, referencing his extensive experience in immigration enforcement.
Homan also described the legal framework guiding such investigations. “ICE is enforcing the law that Congress wrote. I mean, these are all laws that are in statute in the Immigration Nationality Act, which was written by Congress, enacted by Congress, and signed by the president. ICE, HSI, DHS—none of us are making this up. Our job is to enforce the laws enacted by Congress, and that’s exactly what we are going to do,” Homan said. He emphasized that the investigation is not politically motivated, stating there is “nothing political about it.”
The denaturalization process is rare and typically reserved for cases involving clear evidence of fraud or misrepresentation. If citizenship is revoked, the individual may become subject to removal proceedings and possible deportation, depending on the circumstances of their original entry and subsequent actions.
Omar’s Response and Broader Context
Rep. Omar and her staff have consistently denied the allegations. Her chief of staff previously described the claims as a “ridiculous lie,” and Omar herself has repeatedly rejected any suggestion of wrongdoing. Despite the ongoing investigation, no formal charges have been filed, and DHS officials have not indicated when or if further action might be taken.
The investigation comes at a time of heightened scrutiny of immigration enforcement practices and the denaturalization process in the United States. DHS officials have stressed that all enforcement actions are based on existing statutes and legal standards, not on the political status or public profile of any individual. Omar’s case has drawn particular attention due to her position as a sitting member of Congress and the high-profile nature of the allegations.
DHS has not provided a timeline for the investigation, and it remains unclear when additional information or decisions will be made public. The situation continues to evolve, with officials reiterating their commitment to enforcing immigration laws as written and ensuring that all individuals are subject to the same legal standards.
As the investigation proceeds, both supporters and critics of Rep. Omar are closely watching for developments. The outcome could have significant implications not only for Omar herself but also for broader debates about immigration policy, enforcement, and the standards applied to naturalized citizens in the United States.
