Keep in mind that those surrounding #Trump are puppeting him for their own personal, and diverse, goals.
You could see that directly in the Signal leaks.
And so for many of them the #tariffs aren't the end goal. Some of them are using cases like this and the birthright citizenship case as vehicles to nudge US law in the longrun, and not necessarily in bad ways.
This case stands to reinforce the bounds of the nondeligation doctrine, for example, throwing Trump under the bus to guard against overreach by future, actually competent presidents.
... others just want to watch the world burn.
