Federal investigators examining Rep. Ilhan Omar's family history for possible fraud and false statements in immigration paperwork have subpoenaed some of her relatives, The New York Times reported Tuesday, citing people familiar with the investigation. One of the Minnesota Democrat's sisters received a subpoena, the paper said, and so did at least one other member of her family circle.

Fox News said it had also learned that subpoenas were sent to multiple members of Omar's family. Neither report described what records or testimony the subpoenas demand, and neither included a comment from the Justice Department about them. Fox said it had asked the department and Omar's office for comment.

In explaining the step, the Times noted that grand jury subpoenas are used to gather evidence about possible crimes and that receiving one does not mean a person is under investigation. Omar's sister did not reply to the paper's requests for comment.

The subpoenas follow Monday's search of Omar's Washington home by agents of Homeland Security Investigations. The Justice Department confirmed that the agents executed a judicially authorized search warrant as part of an ongoing federal criminal investigation, and people familiar with the matter told the Times that agents carried out boxes of documents.

The full scope of the inquiry is unclear. According to the Times, it focuses in part on whether Omar's late father lied on immigration forms, or left information off them, before he became a U.S. citizen. Omar has said she became a citizen through her father's naturalization in 2000, before she turned 18.

She has repeatedly denied wrongdoing on immigration matters. In a post on X after Monday's search, she called it "an attempt to target political enemies and weaponize federal law enforcement" and wrote, "For ten years, Trump has targeted me with baseless lies and smear campaigns. This is just the latest escalation in his campaign of political intimidation." She said she would not be silenced.

Federal authorities have scrutinized Omar's immigration history for more than a decade, the Times reported, and none of those inquiries has led to charges.

President Trump kept up his criticism of Omar on Tuesday. In a statement the White House shared on X, he questioned changes in her financial filings and said, "America wants answers, and we want them, NOW!" The Times reported that he also suggested she had committed immigration fraud.

Vice President JD Vance, who said in a March interview that Omar was "definitely guilty" of immigration fraud, said Tuesday that he had no advance knowledge of the search. "The president and I largely try to stay out of Department of Justice investigations and other prosecutions," Vance said. "If there's a real case there, we're going to follow the facts. If there's not a real case there, then we won't."

The subpoenas come a few weeks before Election Day. Law enforcement officials usually hold back from overt steps that could be seen as helping or hurting a candidate during that stretch, the Times noted, although prosecutors have sometimes gone ahead when they had reason to believe evidence could be destroyed or other crimes committed. Norman Eisen, a lawyer who has filed repeated lawsuits against the Trump administration in recent months, said on social media Tuesday that a nonprofit group he works for had asked the Office of Special Counsel to examine whether administration officials violated the Hatch Act by "orchestrating" the search.

Omar has represented a solidly Democratic district that includes Minneapolis since 2019. She won her primary in a landslide this year and faces no competitive Republican challenger in November.

Her financial disclosures are the focus of a separate federal inquiry. Jeanine Pirro, the U.S. attorney for the District of Columbia, said Tuesday that her office is investigating those filings, and it is not clear whether that inquiry has any connection to Monday's search.
