Congresswoman Ilhan (4)
I believe the answer is:
omar
'congresswoman ilhan' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for omar that I've seen before include "- Khayyam, Persian poet, astronomer and mathematician" , "- - Sharif (films)" , "- Khayyam, Pers. poet" , "Old caliph" , "and 16 Down: Persian poet" .)
