The Trump administration found not one judge or panel of judges who agreed with their opinion ... until SCOTUS, where it found three.
Including Clarence, whose "hilarious" dissent says that undocumented persons are not subject to the jurisdiction of the United States, which might be of note to ICE.
“Unperson” vibes. If their existence is illegal, then they have no rights. Clarence would never consider that the definition of who is or is not legal would expand, though. Too busy driving his RV to the airport to fly to an island retreat.
