Federal authorities have intensified their investigation into Minnesota Representative Ilhan Omar amid allegations of immigration fraud and financial improprieties, with DNA evidence playing a key role in the ongoing probe. The inquiry has prompted responses from high-profile political figures and raised questions about potential legal consequences for the congresswoman.

Sources familiar with the investigation confirmed that prosecutors plan to use DNA test results in their case against Omar. The tests reportedly indicate a 99.999998 percent probability that Omar and her former husband, Ahmed Nur Said Elmi, are biological siblings. Omar, who is Somalian-born, has faced longstanding rumors and accusations that she married her brother to obtain immigration benefits, an allegation she has denied.

This week, court documents filed in the United States District Court for the District of Columbia revealed for the first time an alias associated with Omar: Ilhan Nur Said Elmi, the surname she shares with Elmi. The documents referenced a search conducted on Oct. 12 at Omar’s Washington, D.C., residence as part of the investigation. Additionally, authorities seized Omar’s phone during a separate search of her Minnesota home on the same date. Federal agents from Homeland Security Investigations and the Department of Justice have also questioned Omar’s sister, Sahra Noor, and issued over a dozen grand jury subpoenas in connection with the case.

Omar’s legal team has condemned the investigation as politically motivated. Former President Barack Obama expressed strong opposition on social media, calling the probe “appalling” and asserting that Omar is being targeted for her political views. Obama emphasized that government agencies should not selectively pursue individuals based on their speech or beliefs. However, it is notable that the search warrants were authorized by Magistrate Judge Matthew Sharbaugh, an appointee of Obama’s administration, who is also a known donor to former Secretary of State Hillary Clinton.

In parallel to immigration-related questions, separate financial allegations have surfaced. Representative James Comer, Republican chair of the House Oversight Committee, accused Omar and her husband, Tim Mynett, of fraud related to their winery business. Comer stated that the winery was shuttered earlier this year amid claims that it sold empty barrels to investors. He has also scrutinized Omar’s financial disclosures, highlighting an unexplained fluctuation in the reported net worth of Omar and Mynett from approximately $51,000 in 2023 to an estimated $30 million in 2024, which then purportedly dropped back to five figures after the committee initiated its inquiry. A separate financial investigation is reportedly being handled by the U.S. Attorney’s Office in Washington, led by Janine Pirro.

Minnesota’s Somali immigrant community has previously been subject to immigration fraud investigations, including a 2008 State Department moratorium on family reunification programs due to concerns over falsified biological relationships. The region, home to the largest Somali population in the United States, has seen increased political scrutiny amid rising welfare fraud cases and growing electoral competition. Republican Senate candidate Michele Tafoya has capitalized on these issues in her campaign against incumbent Lieutenant Governor Peggy Flanagan.

President Donald Trump weighed in from the White House, suggesting that Omar could face criminal charges or deportation depending on the outcome of the investigation. Trump characterized her as disloyal to the United States and criticized her country of origin.

Legal experts note that if Omar is found guilty of immigration fraud, she could face denaturalization and removal from Congress. Nevertheless, political analysts suggest that any vacancy would likely be filled by another Democrat in her district. The case remains ongoing, with authorities continuing to gather evidence amid heightened political attention.

This investigation underscores a broader emphasis on immigration enforcement, reflecting policies since the Trump administration aimed at reducing illegal immigration, enhancing vetting procedures, and combating welfare fraud networks. Despite these efforts, polls continue to show Democratic candidates holding an advantage in voter confidence on immigration issues.
