That they weren't being deported is tautologically self-evident.
These are literally people who:
- Weren't effectively detained on an ICE hold after being arrested for some criminal act;
- Weren't picked up by ICE (due to the lack of ICE hold);
- Weren't pursued by ICE.
That's why they're still in the country, and being deported now.
But okay, sure, have it your way: Biden was finding and deporting (some of) these folks. So what's your objection to Trump finding and deporting (some more of) these folks, with a focus on bad actors that somehow slipped through Biden's grasp?
