A couple of good articles I found this morning:
https://www.justice.gov/opa/speech/attorney-general-jeff-sessions-delivers-remarks-eighth-circuit-judicial-conference
This one gives a little more insight into Sessions' intent, I think, and maybe explains the 'slow walk' a little better.
Then, I found this article from George Ure (Urban Survival) that talks about 'McCarthyism' in a little more clear detail:
https://www.justice.gov/opa/speech/attorney-general-jeff-sessions-delivers-remarks-eighth-circuit-judicial-conference
This one deals with some of the 'changes' that occurred with that whole mess, and how it's being revisited now by the Leftys.
Both are too long to post in entirety, but I think are worth reading.
