Of course they knew!
Any other scenario is unimaginable.
We are just so used to MSM's cover stories that we can't do anything about, and go on living our lives knowing that they lie to us but unable to do anything about it.
Unless somebody said it about him.
Then it would be anti-semitic and somebody would go to jail for saying it.
More double standards.
We are powerless against these people.
We can't even know for sure if one of our SCOTUSs is actually alive or not.
