The questioning is part of a broader effort by the Trump administration to build a case to strip Omar of her US citizenship and deport her, according to the Wall Street Journal. Investigators are examining whether her birth year was falsified as 1982 instead of 1981 so she could automatically derive citizenship as a 17-year-old minor through her late father, Nur Omar Mohamed, in 2000, as well as claims that she married her brother, Ahmed Nur Said Elmi. Fox News reported that authorities hold Omar's personal passport and DNA—which sources said was not taken from her trash, disputing an earlier NewsNation report—while the New York Post reported that the DNA samples confirm she wed her brother.
Omar faces parallel scrutiny of her finances after DC US Attorney Jeanine Pirro confirmed her office is investigating disclosures that valued businesses tied to Omar's husband, Tim Mynett, at up to $30 million before being amended to under $100,000. House Oversight Committee Chairman James Comer told Fox News that a California winery co-owned by Mynett was shut down for fraud after "selling investors barrels of wine to be aged, but there was nothing in the barrels," while White House border czar Tom Homan separately told Fox News that questions about potential non-immigration offenses in Minnesota were "a question for the FBI." Omar has denied wrongdoing and called the raid "political intimidation," and former President Barack Obama denounced the administration's effort to deport her as "so appalling."
