White House border czar Tom Homan has confirmed that Homeland Security Investigations is conducting an active criminal investigation into Rep. Ilhan Omar, and multiple senior administration officials say denaturalization and deportation remain on the table.
Homan made the confirmation during an appearance on Fox News' "The Sunday Briefing," telling the host he could not share specifics but acknowledged the probe is real and moving forward. "I know things are going on, but I can't give specifics of what's happening," Homan told the program. He went further when pressed, saying he had flagged the matter publicly months earlier.
The investigation centers on long-standing allegations that Omar, a Democrat representing Minnesota, committed immigration fraud, including claims she married her own brother to help him gain entry into the United States. Omar has dismissed the allegations as "bigoted lies" and accused President Trump of being obsessed with her. But the administration's public posture has only hardened, with three of its most senior figures now on the record about the case.
Homan did not hold back about the scope of the probe or the principle behind it. He confirmed ICE's involvement directly, then pointed to the investigative arm doing the work.
"If someone committed an immigration violation, if someone committed marriage fraud or anything like that, regardless if they're a congressman or not, no one's above the law. So, I'll leave it at that. We'll let HSI, Homeland Security Investigations, continue the investigation."
That statement carries weight beyond rhetoric. Homeland Security Investigations, or HSI, is the principal investigative arm of DHS, the federal unit that handles immigration fraud, document fraud, and transnational crime. Homan's decision to name the unit publicly signals the probe has moved past preliminary review.
He also laid out the legal mechanism the government could use if fraud is proven. Denaturalization, the formal revocation of U.S. citizenship, is available when the government can show a naturalized citizen lied or misrepresented material facts during the immigration process. Homan called it "very serious" and noted it has been used repeatedly.
"If someone lies through that process to becoming a citizen, and we can prove they, in fact, lied or misrepresented themselves, we can absolutely denaturalize them. We've done it before many times over the last 40 years I've been around, so it's a process."
The broader federal focus on Minnesota's immigration system adds another layer. Just The News reported that Homan confirmed DHS is pulling records and files tied to Omar, and that the department is conducting a wider review of visa fraud within Minnesota's Somali community. DHS claims that 50 percent of visas in the state are fraudulent, a staggering figure that, if accurate, would represent one of the largest concentrations of immigration fraud in the country.
"We're pulling the records, we're pulling the files. We're looking at it... I'm running that down this week," Homan said, as reported by Just The News. "President Trump has instructed us to go down, and we're going to deep dive all of this, and we're going to hold people accountable."
Homan is not the only senior official speaking publicly. DHS Secretary Markwayne Mullin went further on a podcast appearance, making specific factual claims about Omar's alleged fraud and warning that consequences are coming.
"Something's going to happen.... We know that she married her brother to try to bring him to the United States. We know he now lives in London."
Mullin also raised the possibility of deportation, stating that the investigation could extend beyond the marriage fraud allegation to encompass the broader circumstances under which Omar's family entered the country. "There may be more to this, the whole family migration and possibly some illegal activity for them to come to the United States to begin with," Mullin said. "If we can prove it, that you shouldn't have been here in the first place, we will deport you."
That is a sitting Cabinet secretary publicly stating that a sitting member of Congress could face deportation. The federal probe and deportation threat Mullin described represent an extraordinary escalation, one with few precedents in American political history.
No formal charges have been filed, and no indictment has been announced. The investigation remains ongoing, and Omar has not been arrested or formally accused in any court filing made public. But the volume and specificity of official statements have increased steadily over recent months, moving from general references to pointed claims about marriage fraud, document fraud, and the legal tools available to strip citizenship.
Vice President JD Vance has been the most direct. In a March podcast appearance with conservative commentator Benny Johnson, Vance said he had spoken with White House immigration advisor Stephen Miller about potential legal action against Omar.
"We think Ilhan Omar definitely committed immigration fraud against the United States of America."
By May, Vance added that the Department of Justice was looking into the matter. "You read the things about Ilhan Omar... who she married and whether she didn't marry this person or that person. It certainly seems like something fishy is there, but everybody's entitled to equal justice under the law," Vance said.
The timeline is worth noting. Vance's March statement came first, identifying the administration's belief that fraud occurred. His May statement confirmed DOJ involvement. Homan's appearance on "The Sunday Briefing" then confirmed HSI is actively running the investigation and characterized it as criminal. Each step has been more specific than the last.
Earlier this year, DHS disclosed that its investigation into Omar's immigration history was formally underway. And separate reporting revealed that ICE has withheld records tied to Omar, citing active enforcement proceedings, a procedural move that typically indicates a live, ongoing case rather than a closed review.
Omar has pushed back. In December, she took to social media to dismiss the fraud claims as "bigoted lies" and accused Trump of being obsessed with her. She has not, based on available reporting, addressed the specific claims made by Mullin about her alleged brother or his reported residence in London.
Fox News Digital reached out to Omar's office for comment. No response was included in the reporting.
The congresswoman's defense has remained consistent over the years: the marriage fraud allegations are politically motivated attacks rooted in bigotry. But the administration's approach has shifted from political rhetoric to operational language. Homan did not frame the matter as a political dispute. He framed it as a law enforcement investigation with a defined process and a named investigative unit.
Meanwhile, the Washington Examiner reported that Homan confirmed an ICE personnel surge is headed to Minnesota's Twin Cities, linked to the broader Somali fraud investigation. Homan declined to share operational details for security reasons, but the deployment signals that federal enforcement activity in Omar's home district is intensifying beyond the individual case.
President Trump himself weighed in on Truth Social, stating that the DOJ and Congress are reviewing Omar and questioning how she went from arriving in the country "with NOTHING" to being "reportedly worth more than 44 Million Dollars," as Breitbart reported. Trump also referenced a separate investigation into alleged welfare fraud in Minnesota exceeding $20 billion.
An ethics watchdog has also demanded that the House Ethics Committee obtain Omar's financial records after the panel voted to drop its own probe, adding yet another front of scrutiny to the legal and political pressure surrounding the congresswoman.
Several key questions remain unanswered. No charges have been filed. No court documents have been made public. The specific evidence DHS and HSI have gathered has not been disclosed. And the identity of the man Mullin described as Omar's brother, allegedly now living in London, has not been confirmed through official records in any of the available reporting.
But the distinction between political talk and federal action is narrowing fast. Three senior administration officials, the border czar, the DHS secretary, and the vice president, have now spoken publicly about the case. Homan named the investigative unit. Mullin stated specific factual claims about the alleged fraud. Vance said the DOJ is involved. And ICE is surging personnel into the Twin Cities.
Omar calls it bigotry. The administration calls it law enforcement. One of those claims will be tested, and if DHS can prove what its leaders say they believe, the consequences for a sitting member of Congress would be without modern precedent.
Nobody in America is supposed to be above the law. The question now is whether the people who say that the loudest are finally prepared to prove it.
