Kick her out.
Ilhan Omar being a lying, incestuous Congressperson is a symptom, not a cause.
Unfettered immigration allowing growth of a Somali enclave large enough in a district to win a Congressional election is the problem. She just happened to be the one nominated and elected. If it wasn’t her, it would be someone just like her.
You can kick her out all you want, but in the words of The Who, “meet the new boss, same as the old boss”.
