Just now at Arizona Rally:
"(Biden) is lucky I have Bill Barr as Attorney General. He is a very fair man. A good man". (might not be a precise quote)
This was a WARNING to Biden. They are negotiating. Trump said Trump gets angry some time. AG Barr is positioned as good cop, Trump is bad cop.
It's on.
What if POTUS was just trying to give some palatable excuse as to why Barr isn't going after it?
It didn't sound like that. It sounded like a message to Biden. He changed his tone just a little bit. I felt it/heard it - and others did, too.
