If I recall properly (I am not an attorney) the charge sedition is a result of an old Woodrow Wilson war time act, I think it's the espionage act. Anyway if that's accurate I don't believe it has ever actually faced a supreme court challenge. With John Roberts seemingly compromised and siding with leftists it's possible sedition would survive a supreme court challenge and could be struck down. That could actually put the rest of the Act on the chopping block also.
