Rumors about Ilhan Omar’s marriages have floated around Minneapolis for a full decade.
She denied them. Fact-checkers waved them off. Then federal agents carried boxes out of her Washington, DC home.
And now investigators reportedly hold one thing that could rewrite the whole story.
Prosecutors Reportedly Want a Lab Test to Settle a 17-Year-Old Question
Federal prosecutors plan to use DNA evidence in their case against US Representative Ilhan Omar (D-MN), according to sources who spoke with the New York Post. The goal, those sources say, is to test one of the oldest and strangest allegations in American politics: that the Minnesota Democrat married her own brother.
Omar wed a British citizen named Ahmed Nur Said Elmi in 2009. Critics have claimed for years that Elmi is her biological sibling and that the marriage existed to help him land a green card. Omar has flatly denied it every time the question comes up, going back to her first run for the Minnesota House in 2016.
One source told the Post the DNA evidence is critical to proving the sibling allegation.
Nobody has said publicly how or when investigators collected it. Another source shot down early chatter that agents went “dumpster diving” for samples.
The DNA report surfaced about a week after Homeland Security Investigations agents searched Omar’s Washington, DC home in mid-October 2026. Photographers caught agents walking out with boxes marked “Seized Property Evidence.” A Department of Justice spokesperson confirmed that agents “executed a judicially authorized search warrant secured by the Department of Justice.”
Elmi’s own paper trail adds a wrinkle. According to The Washington Post, he filed for a marriage-based green card and then pulled the application in 2019 after US Citizenship and Immigration Services asked for more evidence about the marriage. He and Omar had already divorced in 2017.
And the household arrangements only get messier from there. Omar held a religious wedding ceremony with Ahmed Hirsi back in 2002, but she didn’t legally marry him until her divorce from Elmi became final. She filed joint tax returns with Hirsi in 2014 and 2015 while she remained legally married to Elmi. Documents the Post reviewed earlier suggest all three adults shared a residence at one point.
Try explaining that arrangement to a county clerk in Alabama.
The Case Reaches Back Further Than One Marriage
The marriage question sits inside a much bigger probe. Sources previously told reporters that investigators are also examining whether Omar or her late father, Nur Omar Mohamed, misrepresented her birth date so she could become a citizen when he naturalized in 2000. The family left war-torn Somalia and arrived in America in 1995.
That detail matters for a simple legal reason. The statute of limitations runs longer for lying on immigration paperwork than it does for a fraudulent marriage.
But a false-statements case carries a heavier price too. A sham marriage conviction wouldn’t automatically threaten Omar’s citizenship. Lies repeated on passport renewals or other federal forms could.
Prosecutors appear ready to thread that needle with a conspiracy charge. Former federal prosecutor Neama Rahmani explained the strategy plainly. “If you argue a conspiracy, you can allege overt acts in furtherance of the conspiracy that are outside the statute of limitations,” he said.
Rahmani also pointed out that Omar’s father, who has since died, would count as an unindicted co-conspirator. He added that a warrant like this one had to come “from the highest levels of the DOJ.”
President Trump’s border czar Tom Homan says the feds have built “a strong case” that could lead the administration to seek Omar’s denaturalization.
US Attorney for Washington, DC Jeanine Pirro runs a separate track focused on Omar’s finances, including an accounting “discrepancy” in House disclosures that knocked tens of millions of dollars off the congresswoman’s reported net worth. Pirro didn’t mince words on Fox News. “That judge would not have signed that warrant unless there was probable cause,” she said. “If there was a crime committed, it will be prosecuted.”
House Oversight Committee Chairman James Comer (R-KY) sounded the same note. “From our initial investigation of Omar and her financial disclosure form, there are multiple fronts where you could get a search warrant issued,” Comer told Fox News.
Democrats Rediscover Due Process Right on Schedule
Omar’s camp answered exactly the way anyone could have predicted. “Make no mistake: this is an attempt to target political enemies and weaponize federal law enforcement,” she wrote after the search.
Her attorneys, Amy Jeffress and Joshua Matz, fired off a letter demanding the Justice Department return everything agents took. They claim agents ignored a magistrate judge’s special instructions and broke longstanding policy against such actions close to an election. “President Trump has made no secret of his desire to target Representative Omar for criminal investigation and deportation as retribution for her political advocacy,” they wrote.
The Justice Department hit back fast. A spokesperson called the letter “riddled with false allegations and inaccuracies” and added, “Leaking a letter to the press right after sending it is not good faith. It is a publicity play.”
Fairness demands the rest of the record, too. A former immigration official told The Washington Post that investigators during the first Trump administration looked at the sibling allegation and came up short on evidence. Omar faces no charges. Her lawyers insist there is “no legitimate basis for any suggestion that she has violated any law concerning her citizenship status.”
But the “weaponization” line carries a certain irony coming from Democrats.
Attorney General Merrick Garland appointed Special Counsel Jack Smith, who rushed constitutionally dubious charges against Donald Trump into a Washington, DC courtroom with the 2024 election circled on the calendar. Smith’s team chased Trump’s aides and lawyers along the way. Democrats called all of that accountability. Nobody in party leadership fretted out loud about election-season timing back then.
And this probe didn’t spring up overnight. A current official told NPR it stretches back years and includes whistleblower complaints, and the Minnesota US Attorney’s Office got the ball rolling. Back in January 2026, US Representative Tim Burchett (R-TN) asked the House Intelligence Committee to subpoena and release Omar’s immigration records.
So the “Trump just woke up angry one morning” theory has some holes in it.
What a Lab Result Could Mean for Every Citizenship File in America
Maybe the DNA clears her. That would at least bury a rumor that has hung over Minnesota politics since before most Americans knew her name.
But if the results point the other way, the fallout won’t stop at one congressional office. American citizenship works on trust. Applicants swear to the truth on federal forms, and US Citizenship and Immigration Services processes mountains of those forms with thin verification. If a questionable file can follow someone all the way to the House floor, the obvious next question is how many others never got a second look.
The law already answers what happens when someone obtains naturalization through fraud. Federal courts can revoke it. Nobody has ever done that to a sitting member of Congress, and the Post noted the move would be unprecedented.
And unprecedented is the word Democrats will lean on hard. Expect the party to treat any indictment as an attack on every naturalized American, as though the honest millions and the alleged liars belong in the same bucket. They don’t.
The next stop appears to be a grand jury. Sources say prosecutors believe they have enough for a conspiracy charge, with the search and the DNA serving as the backbone.
One test tube may end up doing what a decade of denials, fact-checks, and press releases never managed to do.
Settle it.
