Representative Ilhan Omar (D-MN) has significantly bolstered her legal defense team, retaining two prominent Washington litigators as federal investigators intensify a probe into her immigration and naturalization history. The Minnesota congresswoman has turned to Amy Jeffress and Joshua Matz, both partners at the law firm Hecker Fink, to navigate a criminal investigation that has already resulted in the seizure of her personal property.
The selection of Jeffress and Matz brings high-level experience with Democratic legal priorities and federal oversight to Omar’s defense. Jeffress, who became the personal attorney for President Joe Biden in 2025 after replacing Bob Bauer, has a history of involvement in high-stakes political cases. Her previous work includes representing former FBI lawyer Lisa Page during the controversy surrounding anti-Trump text messages and serving as outside counsel for the House January 6 committee. Matz is equally seasoned in congressional legal battles, having served as counsel to the House Judiciary Committee during both impeachment proceedings against former President Donald Trump. He has also represented major academic institutions, including Brown, Columbia, and New York universities, in litigation against the previous administration.
While neither attorney’s primary practice is focused on immigration law, both specialize in government investigations and constitutional disputes. Their involvement comes in the wake of a significant escalation by federal authorities. On October 12, agents from Homeland Security Investigations (HSI) executed a search warrant at Omar’s home in Washington. During the raid, investigators seized her smartphone, passport, computers, and several notebooks.
The federal probe is reportedly centered on several long-standing allegations regarding Omar’s naturalization process. Investigators are examining whether the congresswoman or her late father provided inaccurate information regarding her age on official paperwork. Furthermore, authorities are revisiting claims concerning Omar’s 2009 marriage to Ahmed Nur Said Elmi, specifically investigating allegations that the union may have involved her brother. A recent Department of Justice filing associated with the search warrant notably listed the congresswoman as “Ilhan Nur Said Elmi, a/k/a Ilhan Abdullahi Omar,” a designation provided without further explanation in the legal documents.
Omar’s new legal team has already begun a public and formal pushback against the investigation. In a letter sent to the Department of Justice on October 16, Jeffress and Matz demanded the immediate return of all property seized during the home search. The attorneys accused federal agents of failing to follow specific search protocols established by a magistrate judge. The letter characterized the investigation as “vindictive, retributive, and politically motivated,” arguing that the probe into one of the administration’s vocal critics violates constitutional protections and threatens the established separation of powers.
The legal battle is creating significant financial and political pressure for Omar. On Tuesday, the congresswoman posted a video to TikTok requesting donations from her supporters to help cover what she described as a “very expensive and challenging time.” Campaign financial disclosures from the October 15 deadline did not yet reflect any payments to Hecker Fink or the individual attorneys, suggesting the financial burden of the defense is a mounting concern.
Politically, the investigation has drawn sharp reactions from opposition figures. On Thursday, Donald Trump called for Omar’s immediate resignation. Border czar Tom Homan has also weighed in on the potential consequences of the probe, suggesting that if fraud is substantiated, Omar could face the possibility of denaturalization and subsequent deportation.
Omar has consistently denied any wrongdoing regarding her immigration history or her 2009 marriage. As the legal team prepares for further proceedings, the case remains a high-profile intersection of federal criminal law and partisan politics.
