Could be what they’re waiting for.
It could be another of Trump’s chess moves. No one understands how he thinks, no matter how many times they discuss it.
My guess as that he has let Mueller run rampant, get so sure that he cant’t be touched and therefore most likely to make a bad mistake. At that point, hang Mueller high.
Certainly Mueller believes that he is the right hand of God. The FBI raid, the demand for all Sean Spicer’s notes. etc., shows Mueller believes his powers are infinite.
That mindset usually leads to downfall.
In short, Trump may have set Mueller up by giving him the rope to hang himself.
I hope so.
