First, waterboarding isn’t okay for anyone. Second, Brennan didn't start the waterboarding program, and he wasn’t Haspel’s boss until 10 years after her waterboarding days. Third, Brennan and Haspel played very different roles in the CIA’s waterboarding program. Now, I’m not going to say that Brennan isn’t complicit in the waterboarding program. He knew about it and supported it for a long time. But Brennan spent most of his career either as an analyst or as a supervisor of other analysts, whereas Haspel was an agent who did the actual torturing (and ordered others to do it). Fourth, while Brennan initially supported the waterboarding program, he had changed his mind about it by 2009 (or possibly earlier, but 2009 is when he first made public comments about it). Haspel has never publicly stated any change of mind about waterboarding, destroyed evidence regarding the CIA’s waterboarding program, and has refused to denounce the CIA’s use of waterboarding. All she has promised is to not violate the law, which now clearly defines waterboarding as torture. These differences won’t seem like much to many people, but they are exactly the kinds of hairs that politicians love to split. And in any case, you are overlooking the much deeper hypocrisies here (e.g., that the top politicians from both parties were briefed about the program and raised no objections to it—even in private—until it became public knowledge) in favor of much more superficial complaints.
