WASHINGTON, Oct. 15 -- The search of Rep. Ilhan Omar's home on Monday was not where the investigation began. Several of her relatives had already received grand jury subpoenas days earlier, CBS News reported, which turns a single raid into a family-wide inquiry.

The subpoenas were issued on a Friday, a few days before agents from Homeland Security Investigations searched Omar's Washington house. The criminal probe looks at possible fraud and false statements in immigration paperwork, some of it dating to Omar's childhood and completed by her late father. Two sources told CBS that HSI also took her personal cell phone. Grand jury subpoenas do not by themselves mean the recipients are suspected of wrongdoing, Fox News noted.
