The New York Post just published the marriage certificate of the sister of Ilhan Omarβs βbrother husbandβ who lived with him in the UK. She lists their father as βNur Said Elmiβ and his says he is a βmilitary officerβ.
This lines up with Leila Nur Said also being Ilhanβs sister, which even further proves Ahmed Nur Said Elmi, who Ilhan married, is also her brother.
