Even worse the Supreme Court has actively made it quite difficult to pursue bribery cases recently basically requiring the parties to be stupid enough to put in writing "I will pay you X to vote Y on Z" and then "This is the payment for your vote that would not have happened if you had not voted Y on Z".
I mean the Chief Justice was asked by Congress - "It seems that every other part of the federal court system has ethics guidelines and processes, but not the Supreme Court. It seems reasonable that the highest Court in our land should have those." And he replied, almost verbatim, "We're not going to do that and we're offended that you feel the need to ask."
And the Supreme Court did this because the Republican Justices were caught accepting bribes. It's become just another corrupt Republican institution, the same as the Presidency and Congress.
