To be explicitly precise, the attorney in this case was doing her job. No more, no less. To rise to the level of abuse of power would require that she pursue a case that she could not win, or to withhold information needed for a proper defense, Etc.

I don't defend her actions, but neither do I presume to know her intentions. I do not imagine her cackling with glee at this outcome. Vilifying her, as an individual doing her job, is not warranted. That leaves the organization which gave her that job and ordered her to do it.

It is by that reasoning that I do believe it is about the "Justice Department" and not a particular prosecuting attorney within the department.
