Well, the thing about being a criminal is that it means you’ve been convicted of a crime.
Trump is a criminal. But he was born in the US to US citizens.
The goal is to make all sorts of things crimes such that it’s almost impossible to function in the US as a foreigner without committing a crime. At that point, the government can choose the people to deport at their whim.
Since birthright citizenship is being struck down, and this government interprets the constitution as only applicable to citizens, expect Trump to attempt again to pass legislation for more types of citizenship nullification.
One tricky bit is, if you’re declared legally dead, you immediately become an illegal resident if you’re still alive. And DOGE has already declared a number of people dead by misinterpreting a few databases.
