What we know about the criminal investigation into US Congresswoman Ilhan Omar

Key Points:

• US government officials raided Minnesota Congresswoman Ilhan Omar's Washington DC home as part of a federal criminal investigation, with a court-approved search warrant, though the exact nature of the probe remains unclear.
• The investigation reportedly centers on Omar's US citizenship, including questions about whether her age was misrepresented on her citizenship application and suspicions around her marriages, which she denies, calling the probes "complete shams."
• Omar, who became a naturalized US citizen in 2000 after arriving from Kenya as a refugee, faces scrutiny partly due to allegations that her father may have misrepresented her age on immigration documents; her father has also been accused of misrepresenting his background.
• The investigation aligns with a broader trend under the Trump administration of increased denaturalisation lawsuits aimed at revoking citizenship for alleged immigration fraud, raising concerns about potential deportation.
• Omar and her supporters condemn the investigation as politically motivated intimidation ahead of the midterm elections, while former President Trump has publicly called for her deportation and made disparaging remarks about Somalis in the US.
