Federal investigators found evidence Rep. Ilhan Omar entered a marriage with a man believed to be her brother in 2016, and the case stalled on the statute of limitations before resurfacing in a new raid.
The FBI and Department of Homeland Security opened the inquiry while Omar was still chasing a seat in the Minnesota legislature. Officials examined her marriage to Ahmed Nur Said Elmi and, according to reporting first carried by the New York Times and confirmed by the New York Post, uncovered evidence the union was not what it appeared.
Prosecutors later decided any potential crime fell outside the five-year statute of limitations. The file went quiet. A source familiar with the probe said a Biden-appointed U.S. attorney in Minnesota shut related efforts down shortly after taking office in 2021. Now federal agents are back on the case, and the questions Omar long dismissed have returned with warrants and seized devices.
Fox News reported that Obama’s FBI and DHS began the work in the summer of 2016 and that officials “found some evidence that [the marriage] was fraudulent.” The earlier probe closed because of the statute of limitations, not because investigators cleared the record.
That timeline matters. The inquiry did not start under a Republican Justice Department. It started under Democrats, then stalled, then got closed out again after the 2020 election change in Minnesota’s U.S. attorney’s office, a sequence that has left taxpayers wondering who decided immigration fraud questions were too old to pursue.
A New York Times account of the Obama-era findings put the core claim in plain view years before the latest search warrant. Omar has insisted the brother-marriage allegations are a racist conspiracy theory pushed by the far right. Her office has kept that line as agents moved from old paper files to her front door.
"Rep. Omar has repeatedly and unequivocally denied this baseless, disgusting conspiracy theory," an Omar spokesperson said.
The Post’s reporting includes an account from a friend of Ahmed Hirsi, Omar’s first husband. The friend said Hirsi described Elmi as his wife’s brother from London and said Ilhan had embarrassed the family by bringing him into their lives.
"it was his wife’s brother from London and that Ilhan had ‘embarrassed all of us by bringing him here’. Ahmed used very strong words and said it was ‘disgusting.’"
The same friend said Hirsi explained the legal marriage in blunt terms: she married Elmi to get him papers, while Hirsi remained only Islamically married to her. Elmi came to live with Omar and Hirsi in Minnesota in 2009 and left around 2012. After Elmi left, the friend said, Hirsi “praised God for taking him away from his family.”
Community talk in Minneapolis, as the friend recalled it, spread fast once people realized who the new arrival was. The friend also described public arguments between Omar and Hirsi over the brother. None of that gossip is a court finding. It is the kind of witness narrative investigators weigh when marriage and immigration paperwork do not line up.
Earlier this month, federal agents executed a search warrant at the Washington, D.C., home Omar shares with her current husband, Tim Mynett. They seized her cellphone, notebooks, personal computers, and her passport. Fox News placed the Homeland Security Investigations raid on Oct. 12 and tied the new work to scrutiny of whether Omar or her father committed immigration fraud on her citizenship application.
Sources told the Post that investigators are examining whether Omar was part of a family conspiracy to commit immigration fraud, a path that could point toward denaturalization and deportation if proven. Criminal charges for alleged immigration fraud generally must land within 10 years; alleged false statements to officials sit under a five-year clock. Civil denaturalization does not face the same statute-of-limitations wall.
That legal difference is why the old 2016 file still matters. A case that looked “too old” for criminal charging can still feed a civil effort to strip citizenship if the government builds a clean record. Readers tracking what charges and denaturalization could look like already know the stakes are not theoretical.
Omar has long maintained she became a U.S. citizen at 17 when her father, Nur Omar Mohamed, was naturalized in 2000. Some records list her birthdate as Oct. 4, 1981; others list the same date in 1982. After she won her House seat, her staff in spring 2019 pressed the Minnesota Legislative Reference Library, the Biographical Directory of the United States Congress, and Wikipedia to record 1982 rather than 1981.
Her campaign had told the Associated Press the previous fall that she did not have a birth certificate because her family was displaced by Somalia’s long civil war. The Wall Street Journal, as relayed in the Post’s reporting, said Homeland Security Investigations officials were tipped during the Biden years about potential date fudging and declined to move forward for lack of evidence at the time.
Separate reporting has also flagged identity and naming questions as the wider probe expands, including a federal motion listing Omar under a different name. Paper trails that shift after an election invite hard questions from any administration serious about immigration enforcement.
President Trump’s Justice Department has filed almost 200 civil denaturalization cases since January 2025, described in the Post’s account as a record pace. The department has publicized large batches of cases aimed at stripping citizenship from people who obtained it through fraud or serious crime. That tool does not need the same charging clock that boxed in the 2016 prosecutors.
Border officials and former prosecutors have already sketched how a citizenship case against a sitting member of Congress would have to be built, what the government must prove, and what removal could follow if a court agrees. Coverage of those standards, including how a Trump team could pursue citizenship stripping, has kept the legal pathway in public view while agents hold Omar’s passport and devices.
An ex-prosecutor’s breakdown of the proof required underscores the same point the statute books make: civil denaturalization is slower and documentary, not a press-conference stunt. It rises or falls on marriage records, immigration filings, and sworn statements, the very categories the 2016 agents were already examining.
The Post noted it is not immediately clear what specific evidence the 2016 investigators collected on the marriage to Elmi. Case numbers, full charging memos, and complete marriage or immigration filings are not laid out in the public reporting package. The friend of Hirsi remains unnamed. So does the source who described the 2021 shutdown inside the Minnesota U.S. attorney’s office.
What is on the record is enough to explain why the story will not die. Federal agents under Obama found evidence of a fraudulent marriage. Prosecutors cited the five-year limit and stopped. A Biden-era U.S. attorney, per a source familiar with the probe, shut related work down. Trump-era agents have since walked out of Omar’s D.C. home with her phone, computers, notebooks, and passport while examining a possible family immigration-fraud conspiracy.
Omar’s defense remains the same blanket denial she has used for years. The government’s tools have changed. Civil denaturalization does not expire the way the old criminal clock did, and the documents seized this month will either close the gap or leave the congresswoman facing the same unanswered questions in a courtroom instead of a campaign interview.
When marriage, immigration paperwork, and sworn citizenship claims do not match, voters deserve a full accounting, not another quiet burial of the file.
