If true and there is evidence then both Roberts and Breyer will need to recuse at least
Impeachment is a possibility but if there is real proof that SCOTUS justices were conspiring to sabotage President Trump's re election then they could and should be arrested and jailed.
If for no other reason, for their own safety. Can you imagine how people would react?
Lots of stuff going on behind the scenes, it seems.
There's a saying goin' round.
"We have it all".
There is likely more evidence of Roberts' dirty dealings. I think (if true), he's at least gone off the Supreme Court. Maybe Breyer too. Maybe even criminal sedition/treason charges, depending on what else Q and the boys got on him. Maybe two more conservative judges.
Best case scenario.
