The home of Rep. Ilhan Omar, D-Minn, was raided early Monday morning by Homeland Security Investigations (HSI), a source familiar with the matter told Fox News Digital. The raid stems from a criminal fraud investigation into the Somali-born congresswoman's immigration paperwork, which was filled out by her late father when she was a child. Two sources close to the investigation confirmed the details of the probe Thursday, after border czar Tom Homan said in mid-September that the progressive congresswoman was subject to an ongoing "criminal" investigation.
