It looks like the whistleblower being cited can be traced back to a caller to the Hal Turner radio show who claimed he was a Supreme Court clerk and overhead this discussion.
Caller to Hal Turner claiming to be a clerk to a Supreme Court justice. Could be bogus. Decide for yourself:
Hal, as you know I am a clerk for one of the Justices on SCOTUS. Today was like nothing we have ever seen. The justices are arguing loudly behind closed doors.
The Justices met in a closed and sealed room, as is standard.
Usually it is very calm, however today we could hear screaming all the way down the hall.
They met in person, because they didn’t trust telephonic meeting as secure.
Chief Justice Roberts was screaming
“Are you going to be responsible for the rioting if we hear this case?”
“Don’t tell me about Bush v. Gore, we weren’t dealing with riots then”
“You are forgetting what your role here is Neil, and I don’t want to hear from the two junior justices anymore. I will tell you how you will vote.”
Justice Clarence Thomas says “This is the end of Democracy, John.”
When they left the room, Roberts, the Libs and Kavanugh had big smiles. Alito and Thomas were visibly upset. ACB and Gorsuch didn’t seem fazed at all.”
