The DOJ does not have district attorneys and Trump did get rid of U. S. Attorneys just as Clinton and most other presidents before have done. You apparently remember some scuttlebutt about Clinton firing all the U. S. Attorneys when he took office which was no big deal and if you’d checked, you would have learned that.
District - US attorneys terminology confusion on my part essentially the same function! My point is Trump clearly left too many holdovers in place particularly after Rogers warned him of the surveillance & Rush warned him that “Hellary and pals” weren’t going to just let this election thing go. I remember the Rush show where he said Trump said something to the effect’ 6 months after the election it would be accepted.’ It didn’t & they’re still trying to over turn it.
