Federal authorities investigating Minnesota Rep. Ilhan Omar have seized the Democratic lawmaker's phone and issued more than a dozen grand jury subpoenas, including to some of her relatives, according to a person briefed on the probe cited by the Associated Press.

The subpoenas were issued for a grand jury collecting evidence in Minnesota as authorities investigate potential fraud in Omar's immigration paperwork. Homeland Security Investigations agents executed a judicially authorized search warrant at her Washington, D.C. home around 6 a.m. on October 12.

The BBC reports that her mobile phone, notebooks, personal computers and passport were among items seized during the search, which took place while she was home with her husband.

The search landed just 22 days before the November 3 midterms, in which Omar is seeking reelection in Minnesota's 5th District.

The Justice Department has historically sought to avoid overt investigative actions involving candidates within roughly 60 days of an election, an unwritten norm examined in a 2018 inspector general report.

According to Latin Times, the DOJ's Public Integrity Section was consulted, but the unit has been reduced to just two full-time attorneys under the Trump administration.

A person familiar with the operation told CNBC that DOJ officials did not believe the action violated internal policy because the search was not intended to be public, and the warrant reportedly required protocols allowing Omar's legal team to screen seized materials for congressional privilege.

Investigators are examining whether Omar's late father, Nur Omar Mohamed, made false or incomplete statements on immigration forms, with scrutiny centering on Omar's registered birthdate.

As a minor she could gain citizenship automatically through her father's naturalization in 2000, but at 18 she would have had to pursue her own immigration process.

The documents at the heart of the probe predate her political career, some completed more than three decades ago when she was a child refugee. Omar arrived in the U.S. in 1995, became a naturalized citizen in 2000, and has repeatedly denied any wrongdoing.

She has not been charged with a crime.

One day after the home search, D.C. U.S. Attorney Jeanine Pirro confirmed on Fox News that her office is investigating Omar's financial disclosures, saying 'If there was a crime that was committed, it will be prosecuted.'

According to The National News Desk reports carried by WBFF and KEYE, two businesses tied to Omar's husband Tim Mynett showed reported values climbing from as much as $51,000 in 2023 to as high as $30 million the following year.

Omar attributed the surge to accounting errors and amended the filing to a range of $18,004 to $95,000. The Office of Congressional Conduct cleared her of wrongdoing over the episode, though Pirro said that review 'doesn't matter.'

Omar posted on X that the search is 'an attempt to target political enemies and weaponize federal law enforcement' and 'I will not be silenced,' while House Democratic leaders Hakeem Jeffries, Katherine Clark and Pete Aguilar jointly called the raid 'deeply disturbing,' per Latin Times.

Minnesota Governor Tim Walz accused the president of abusing power against political opponents. Notably, former GOP Rep.

Marjorie Taylor Greene broke with the administration, writing on X that officials are 'pretending' to prepare to deport Omar, asking how that would lower gas prices or groceries. The White House responded that Greene 'quit on her constituents,' while Trump said the probe 'has nothing to do with me.'

The Wall Street Journal reports the probe is aimed at building a case to strip Omar of her U.S. citizenship and ultimately deport her, which the BBC notes would fit a broader surge in denaturalization lawsuits requiring the Justice Department to prove a material lie in the application process.

None of the filings, including the warrant, have been made public, and DOJ and DHS have not commented on specifics. Her cellphone remains in federal custody and her relatives face grand jury testimony in Minnesota.

Former FBI special agent Jody Weis told The National News Desk that the high-profile case demands 'as much transparency as possible because transparency breeds legitimacy.' Early voting in Minnesota begins later this week.
