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.
You are absolutely correct. Biden knows Trump has him. So Trump will give him an opportunity to "do the right thing" . Trumps message during the rally today (if you didn't hear it) included something like "I'm only going to say this once". That was meant for Biden, it made no sense in the context of the rally.
