This process is practically unheard of, and it's dismissive to pass it off as just usual practice.
1. Normally, a warrant would have to be issued through a judge with presented probable cause, leading to initial arrest.
2. The charges would be disputed during a hearing with an immigration judge, and if deemed guilty to the charges, they could order to revoke his green card.
3. With no green card, he would then be deported.
In this scenario, there is NO warrant, NO charges, and NO immigration judge hearing regarding his charges. His citizenship was revoked without due process by a political figure exercising a decades-old statute that has remained unused in this manner. There will be no due process during the upcoming immigration hearing; the judge does not issue green cards, they only handle charges and can request to revoke citizenship (which was already done). Khalil will just be deported because he has no permanent residency after it was removed *without* due process.
It is disingenuous to pass this off as normal, as this case is the first of its kind. It is even more disingenuous to say that he has received due process because he hasn't.
