tu quoque

<logic, philosophy of science> the informal fallacy of replying to criticism by arguing that one's opponent is guilty of something equally improper. Example: "Republicans claim that Democrats make illegal use of campaign funds. But they do the same thing themselves, so there is no reason to enforce campaign finance laws." This fallacy is usefully regarded as a special case of the circumstantial ad hominem argument.
