For her specifically she’s trying to get EU /Irish citizenship through her mother’s citizenship (I think).

But yeah your question stands. I read a post a long time ago about taking citizenship away from terrorists and one guy posted that’s really not how it should work. I’m not as well versed as he was but it was basically: The Justice department deals with crimes and punishment, citizenship is just plain membership to a country. If you don’t have citizenship to any country it’s just like you don’t exist in paperwork terms. It doesn’t line up with what the justice system is supposed to do.

Of course Trump just wants to kick people out. So he’ll “negotiate” for random countries to take in people (even not their citizens) or he’ll slap tariffs on them. This is also what asylum is supposed to be for.
