I couldn’t care less what Zero’s cabana boy is “comfortable” with.
Don’t separate them. Send the entire family back.
If the refugee aspect of the border approach is valid, send the entire family to a detention “tent city” where they are to be held until their claim may be fully vetted. This may take a while, so be prepared for a sometimes long-term detention. It may be practical to set up a detention center either on an offshore US island, or on land that is not considered US soil, like the base at Guantanamo. Shuttle the families there immediately upon arrival, then we talk.
NO releases into the general population under any circumstances.
