The federal investigation into Rep. Ilhan Omar has taken a significant turn. According to a report published by The Wall Street Journal on October 14, the Trump administration is attempting to build a legal case that could lead to the loss of her American citizenship and, ultimately, her deportation.
Omar, 44, was born in Somalia, arrived in the United States as a refugee in 1995 and became a U.S. citizen in 2000. A Democratic representative for Minnesota’s 5th Congressional District, which includes Minneapolis, she is running for reelection on November 3.
On October 12, federal agents executed a search warrant at her Washington residence. Investigators reportedly seized her cellphone, passport, personal computers and notebooks. More than a dozen grand jury subpoenas have also been issued, including to members of her family.
No immigration fraud has been established in court, and Omar remains a U.S. citizen and a sitting member of Congress. She denies wrongdoing and describes the investigation as politically motivated.
Federal investigators are examining whether Omar or her father misrepresented her age during the immigration and naturalization process.
According to The Washington Post, investigators are particularly interested in whether Omar was 17 or 18 when her father became a naturalized American citizen in 2000.
The distinction matters because, under the applicable citizenship rules, children meeting certain conditions could acquire U.S. citizenship through a naturalized parent before turning 18.
Investigators are also reviewing information about her father’s background, including his reported military service.
The allegations remain unproven.
Similar claims had previously been examined by Homeland Security investigators during the Biden administration. According to people familiar with that earlier review, officials declined to pursue the case because they lacked sufficient evidence of fraud.
Omar has repeatedly denied misrepresenting her immigration history.
The October 12 search was carried out by Homeland Security Investigations (HSI), the investigative division of U.S. Immigration and Customs Enforcement (ICE).
The Department of Justice confirmed that agents executed a court-authorized search warrant as part of an ongoing federal criminal investigation.
According to the Associated Press, authorities also issued more than a dozen subpoenas seeking testimony before a grand jury in Minnesota.
Separately, Jeanine Pirro, the U.S. attorney for the District of Columbia, confirmed that prosecutors were examining other matters involving Omar, including her financial disclosures.
The precise scope of the investigations has not been fully disclosed, and the existence of a search warrant does not establish criminal wrongdoing.
The central legal question is whether a sitting member of Congress can lose her U.S. citizenship.
President Donald Trump cannot unilaterally revoke an American citizen’s nationality through an executive order or presidential declaration.
However, federal law allows the government to seek denaturalization under specific circumstances, including when citizenship was illegally obtained or secured through material fraud or concealment.
Under 8 U.S.C. § 1451, the government may bring a civil action in federal court to revoke a naturalization. Such proceedings require a demanding standard of proof and judicial review.
Omar’s case presents additional complexities because she acquired citizenship as a minor through her father’s naturalization, rather than through a conventional adult naturalization application.
Legal experts say the government’s case would depend on the evidence surrounding the original immigration documents, the applicable citizenship requirements and any material misrepresentations.
Even if the government successfully challenged her citizenship, deportation would not automatically follow. Separate immigration proceedings and legal protections could apply.
Being a member of Congress does not provide immunity from criminal investigation. But it does not give the executive branch the power to bypass constitutional and statutory protections either.
Born in Mogadishu, Somalia, in 1982, Ilhan Omar fled the country’s civil war with her family.
After spending several years in a refugee camp in Kenya, she arrived in the United States in 1995. Her family eventually settled in Minnesota, home to one of the country’s largest Somali American communities.
Omar became an American citizen in 2000.
In 2018, she was elected to the U.S. House of Representatives, taking office in January 2019.
Alongside Rashida Tlaib of Michigan, she became one of the first two Muslim women elected to Congress. She was also the first African refugee elected to the House.
A member of the progressive group of lawmakers known as The Squad, Omar has been an outspoken critic of Trump’s immigration policies, foreign policy positions and treatment of minority communities.
Her political profile has also made her a frequent target of attacks from the president and his allies.
Ilhan Omar Accuses Trump of Political Intimidation
Following the search of her home, Omar issued a statement on X accusing the administration of using federal law enforcement against political opponents.
She described the investigation as the latest escalation in a decade of attacks by Trump and said:
“I will not be silenced.”
Trump denied any personal involvement in the search, saying the investigation was a matter for the Justice Department.
At an October 12 political event in Ohio, the president again criticized Omar and Somalia. Members of the audience responded with chants calling for her deportation.
The congresswoman’s office has maintained that there is no legitimate basis for stripping her of her citizenship.
Democratic leaders, including House Minority Leader Hakeem Jeffries, have accused the administration of weaponizing federal institutions against political opponents.
Those allegations remain contested. The administration maintains that its investigations concern potential violations of federal law.
The timing of the investigation has intensified the political controversy. On November 3, American voters will elect all 435 members of the House of Representatives and approximately one-third of the Senate.
Omar is seeking another term representing Minnesota’s 5th Congressional District. The search of her home occurred just 22 days before Election Day.
The Justice Department has historically followed internal guidance intended to prevent overt investigative actions from improperly affecting elections, particularly in the final 60 days before voting.
That guidance is not an absolute legal prohibition. Nevertheless, the decision to search the residence of a congressional candidate so close to an election has prompted questions about the department’s independence and the timing of the investigation.
The case comes as Democrats and Republicans compete for control of Congress, with immigration enforcement and executive authority among the issues shaping the national political debate.
Trump’s Denaturalization Campaign Extends Beyond Ilhan Omar
The Omar investigation is part of a broader push by the Trump administration to expand efforts to revoke citizenship obtained through alleged fraud.
According to The Wall Street Journal, the administration has filed more than 200 denaturalization lawsuits during Trump’s second term.
Historically, such cases were relatively rare, with the federal government filing roughly a dozen or fewer annually before the current administration.
The Department of Justice has defended denaturalization efforts as a means of addressing fraud and enforcing immigration law.
Civil rights advocates and immigration attorneys have raised concerns about the potential consequences of expanding these proceedings, particularly when allegations involve decades-old documents and individuals who have spent much of their lives as American citizens.
The distinction between natural-born and naturalized citizens is particularly relevant.
Both groups enjoy fundamental constitutional protections, but citizenship acquired through naturalization can be challenged through specific judicial procedures when the legal requirements are met.
That difference is now central to the investigation involving one of the country’s most recognizable immigrant lawmakers.
The administration’s reported objective does not mean the government has established the legal grounds required to achieve it.
Any attempt to strip Omar of her citizenship would face judicial scrutiny, potential appeals and substantial questions concerning the evidence and the law applicable to her acquisition of citizenship in 2000.
The case nevertheless raises a broader question about American democracy: How secure is naturalized citizenship when the federal government challenges the immigration history of an elected political opponent?
For Omar, the investigation comes at a critical moment in her reelection campaign. For the United States, it places the boundaries of presidential authority, the independence of federal law enforcement and the meaning of American citizenship under renewed scrutiny.
