Why do you assume McCabe escaped?
The determination was made to fight the battle on higher ground rather than waste time and resources
What determination?
Not that you might not be correct as there was lots of speculation about that Durham report, that McCabe might get his just due via that investigation.
But that is just speculation. Nothing official has been stated about this.
“The determination was made to fight the battle on higher ground rather than waste time and resources”
I’m not seeing it. If he has been cleared for his role in the Trump investigation, what else is there?
