Keep in mind that even if I'm wrong about this, a Senate confirmation process is not likely to be considered a major proceeding that would even warrant any examination in the event of a conflict of interest. Ford wasn't a litigant in a civil court case or a defendant in a criminal case, and she would have suffered no loss of any kind no matter how the proceedings turned out.
Nope. Ford was under oath and under penalty of felony. If Katz was there as Ford’s lawyer, she had a duty to protect Ford. If she was there as Fineswine’s lawyer while letting Ford believe she was representing her, that is unethical and probably criminal.
