Find out? We already know they'll rule 5-4 in Trumps favor just off partisan GP.
There's absolutely no reason to think otherwise.
Didn't mean you or me will "find out" just the reveal in general.
The ban was struck down by democratic appointed judges and was based on Trump's campaign statements and it also targeting a specific religion. They tweaked it to kinda not target Muslims but it still does, so now it comes down to if the majority of the court will disregard Trump's campaign words when deceiding.
I will say I don't think this is a 100% slam dunk for Donald.
