I think the whole Benghazi thing and the absurdity of it was crystallized when Jeb Bush went on TV complaining about how Hillary should be held accountable for it and the questioner t-boned him by asking "So then why isn't your brother to blame for 9/11?"
Um, er, um, er... Benghazi!
And as you know there weren't eight investigations into 9/11 stretching out for years, and Dubya wasn't forced to testify under oath on live TV, twice, with the second time being for 11 hours.
