WTF do they have to do with this case? This isn't a criminal proceeding, it's a civil matter.
I've absolutely given up on trying to figure out how our government works. Apparently SCOTUS specifically asked them for their opinion. And here I thought our founders wanted separation of powers, and in particular that the Supreme friggin' Court was intended to be insulated from the ebb and flow of political interests in the other two branches.
I could understand if the Justice Dept decided to file an amicus brief just like everyone else, but I can't understand why SCOTUS specifically sought their opinion.
