Rep. Ilhan Omar is facing federal scrutiny over allegations that could cost her American citizenship, her seat in Congress and potentially her right to remain in the United States.

The investigation reaches back 26 years, to the circumstances under which Omar, a Somali refugee, became an American citizen in 2000. Investigators are examining whether her family’s immigration paperwork contained false information, including questions about her birth date and her father’s naturalization.

A separate financial inquiry has raised questions about business interests belonging to her husband, whose reported valuations jumped into the millions before being revised downward.

Omar denies wrongdoing and accuses President Donald Trump’s administration of targeting her for political reasons. But search warrants, seized records and grand jury subpoenas have taken the allegations beyond the political controversy that has followed her for years.

Federal Agents Search Her Home

On October 12, Homeland Security Investigations agents reportedly searched Omar’s Washington area residence under a court-authorized warrant.

Investigators reportedly seized electronic devices, her passport and documents. More than 12 grand jury subpoenas have reportedly been issued, including to family members, as federal prosecutors in Minnesota examine possible immigration fraud, false statements and conspiracy.

Homeland Security Secretary Markwayne Mullin has described the government’s case as strong and publicly discussed taking the matter before a grand jury.

The investigation concerns records dating to Omar’s arrival in the United States in 1995, after her family fled Somalia’s civil war.

The Birth Date That Could Change Everything

At the center of the investigation is a discrepancy of ONE year.

Omar’s official birth date is October 4, 1982. She became an American citizen in 2000 through her father’s naturalization, reportedly when she was 17.

Under the citizenship law applicable at the time, qualifying children could derive citizenship through a naturalized parent before turning 18.

But older public records, including those maintained by the Minnesota Legislative Reference Library, listed her birth year as 1981.

In 2019, Omar’s congressional staff requested corrections to those records, maintaining that the earlier date was inaccurate.

If Omar was actually born in 1981, she would have turned 18 in October 1999. Depending on when her father naturalized, that could raise serious questions about her eligibility for derivative citizenship.

Investigators would need more than an incorrect public biography. They would have to establish her actual birth date and whether materially false information appeared in the immigration records.

Was Her Father Ever Naturalized?

Another allegation concerns Omar’s father, Nur Omar Mohamed, whose naturalization is central to her account of becoming an American citizen.

In 2023, former congressional candidate AJ Kern obtained responses from U.S. Citizenship and Immigration Services reporting that searches had failed to locate naturalization records for Mohamed, including under alternative names.

The New York Post reported on the documents earlier this month. The responses have fueled questions about whether Mohamed was naturalized in 2000, as Omar has maintained.

A failed records search does not establish that naturalization never occurred. Records may exist under different identifying information, and Mohamed’s original immigration file has not been publicly produced to resolve the dispute.

If Mohamed never became a U.S. citizen, Omar could not have derived citizenship through his naturalization.

Investigators are also examining whether Mohamed accurately disclosed his military service under Somalia’s former ruler, Siad Barre, when applying for immigration benefits.

Mohamed died in 2020. Prosecutors would now have to reconstruct events involving documents and family relationships dating back more than 25 years.

The Allegations Involving Her Former Husband

Federal investigators are reportedly revisiting allegations surrounding Omar’s former husband, Ahmed Nur Said Elmi.

Critics have long claimed that Elmi was Omar’s brother and that their marriage was connected to immigration benefits. Omar has repeatedly denied the allegation, which has not been publicly established.

On October 19, the New York Post reported that investigators had obtained DNA evidence potentially relevant to the alleged family relationship. The newspaper also reported that Omar’s sister, Sahra Noor, had been questioned as the investigation expanded.

The reported DNA findings have not been independently verified, and prosecutors have not publicly disclosed their results.

Any criminal case arising from the marriage allegations would require evidence of fraudulent conduct, not merely questions about family relationships.

A Second Investigation: Where Did the Millions Go?

Omar is separately facing scrutiny over financial disclosures involving her husband, Tim Mynett.

In 2023, Omar reported her husband’s ownership interests in 2 businesses at approximately $15,000 to $51,000. Her original 2024 disclosure, filed in May 2025, valued those interests at between $6 million and $30 million.

Then came another revision.

In March 2026, Omar amended the filing, reporting no net asset value for either business. Her household’s disclosed assets were subsequently estimated at approximately $18,000 to $95,000.

The businesses were Rose Lake Capital, an investment firm, and eStCru, a California winery.

House Oversight Chairman James Comer demanded financial records in February, questioning the increase in reported valuations and seeking information about the companies’ investors and finances.

Omar’s office attributed the discrepancies to accounting errors involving liabilities and ownership valuations.

D.C. U.S. Attorney Jeanine Pirro has confirmed that her office is conducting a separate investigation into Omar’s financial disclosures.

The question for investigators is whether the filings contained accounting mistakes or knowingly false information. No charges have been announced in the financial inquiry.

Could She Lose Her Citizenship?

The government has two principal legal avenues.

The first is criminal prosecution for immigration fraud, false statements or conspiracy. But alleged misconduct dating to 2000 faces substantial statute of limitations obstacles. Criminal naturalization fraud generally carries a 10-year limitation period.

The second is a civil challenge to citizenship.

Civil denaturalization proceedings generally have no statute of limitations, but the government must meet a demanding evidentiary standard. Omar’s derivative citizenship would also raise questions about the appropriate legal procedure for challenging her status.

If federal authorities ultimately established that Omar was not legally a citizen, her position in Congress would be jeopardized. House members must have held U.S. citizenship for at least 7 years.

Deportation would require separate legal proceedings and would not automatically follow a citizenship ruling.

The Political Battle

The investigation comes weeks before the November 3rd midterm elections.

Former President Barack Obama has condemned the administration’s actions, arguing that Omar is being targeted because of her political views. Omar has similarly accused Trump of weaponizing federal law enforcement against an outspoken critic.

Political motivation, however, would not by itself establish that the underlying allegations are false. Equally, search warrants and grand jury subpoenas do not establish guilt.

The scale of the investigation and the administration’s public statements leave little doubt that federal authorities are pursuing Omar aggressively.

The Justice Department has enormous resources at its disposal, and allegations that went unresolved for decades are now receiving renewed scrutiny.

No wrongdoing has been established. But the administration appears determined to pursue the case, with potential consequences ranging from criminal prosecution to loss of citizenship and eventual deportation.

For Omar, the question is whether federal investigators can uncover evidence strong enough to support what the administration appears intent on pursuing.
