Hillary Clinton: Fired from Watergate (1974)
Appointed to Staff of House Judiciary Committee during Watergate. She was "fired" for corrupt and unethical behavior according to Dan Calbrese and Jerry Zeifman[1] (lifelong democrat in charge of the house investigation).
According to Zeifman, "She was an unethical, dishonest lawyer, she conspired to violate the Constitution, the rules of the House, the rules of the Committee, and the rules of confidentiality." Specifically, that she was one of a few individuals trying to deny President Nixon legal counsel and hid/removed evidence (legal files and implied they should be lost). And other things like that.
Ziefman was then smeared by the Hilary campaign machine, WaPo and Snopes, for technically not being able to "fire her" (as she wasn't a direct report to his committee, so he could only recommend she be removed and not "fire" her), and all her unethical behavior might have been at the suggestion of her bosses[2]. But even if true (she was "just following orders"), that doesn't change the ethics/liability according to the bar or common decency. Nor that the pattern of her getting in the middle of scandals, being accused of questionable ethics by those closest to her, and "losing evidence" seemed to follow her through her life.
As does her defenses efforts of her and her supporters trying to get people lost in the weeds of technicalities and to ignore the bigger picture/pattern: a small scandal reveals other bigger scandals/questionable behavior, then someone close to her takes the fall, and we move on to the next scandal around her, while she or someone else to blames the "vast right wing conspiracy" for all of it. (For the record, that "vast right wing conspiracy", is a quote she plagiarized and took credit for, another pattern).
