Holder is probably right, since Trump could not accomplish the prosecutions and convictions of Holder and others who deserved such, during his tenure as President. Of course, Trump had all of the DC/EU/China Swamp to hinder him.
“since Trump could not accomplish the prosecutions and convictions of Holder and others who deserved such”
I think it’s more like, “Trump WOULD not”. Maybe he did, but I don’t recall him bothering. It’s like he believed — and he did believe — that once he was president all of the past would be over and done with. With RATs, it’s never over and done with; they just regroup and find more energy.
