That's a direct result of Miller's demand to ramp up deportations so they started grabbing people who show up for appointments and hearings as they are supposed to (You know following the rules MAGAs claim to want immigrants to do) and rapidly getting them out of the country so they can't be stopped.
Just a reminder when the Trump administration refers to "criminal illegal aliens" they are not referring to people who have committed the crimes we typically think of as being crimes like murder, drug dealing, theft etc.
In Trump land EVERY SINGLE UNDOCUMENTED PERSON AND MOST ASYLUM SEEKERS ARE "CRIMINAL ILLEGAL ALIENS".
