Most of the press releases relate to cases, and the names of the investigators and prosecutors appear.
This release is, on its face, the FBI being political. FBI claims of being apolitical are pure bunk.
I doubt Sessions is in the approval loop for FBI press releases, or even DOJ press releases.
Wray is accountable for this one though, whether it was put out with or without his advance notice and express approval, it represents the agency that he directs.
That Boyd DoJ Congressional interfacer is a long term Sessions minion rather than a long term DoJ insider, but over at the FBI, Sessions likely has no imbeds.
Sessions still needs to be held accountable for the opacity at the DoJ/FBI.
