I would argue that the Deep State, (aka our legal and intelligence agency complex (FBI, NSA, CIA, DOJ, State Dept, etc) Has regularly blackmailed Senators, Presidents, Congressmen/women and Supreme Court Justices since the days of J. Edgar Hoover.
I would wager that if Justice Roberts went on the Lolita Express to enjoy the sexual temptations that Epstein seemed to offer to the rich and powerful of the world, that that indeed with the blackmail item used to influence some of his convoluted legal decisions.
If that is the case, then judicial impeachment proceedings should be started.
I am sure that every new congressman or senator gets assigned a handler whose job is to compromise the freshmen with bribes, blackmail or threats to family members.
