That's certainly a fair criticism. But it's one that was made and acknowledged years ago, as has been essentially everything of note about Benghazi. Clinton's political opponents are free to revisit that issue all they want to, but from a public perspective, in terms of spending taxpayer money and Congress's time on investigating it, Benghazi is done and dusted. There is nothing more to say about it, as Thursday's hearing demonstrated very clearly. I'm sure they'll arrange for another special committee to investigate it next year, though, assuming that Clinton becomes the Democratic nominee.
