So you're telling me the Benghazi-Email-Apocalypse-Witch-Hunt-Monster-Truck-BBQ committees never bothered to read through this email, that came out a year before Benghazi? It has only recently been unearthed despite all her emails having been scrupulously combed through by journalists from every major news source, and like... 10 Select-Committees-On-Trying-To-Make-Hillary-Look-Bad?
That'd be like discovering a lost DaVinci painting was on the wall next to the Statue of David this whole time, and nobody had thought to look left before now.
Forgive me of being highly suspect of your source from a website, whose name is literally a euphemism for bullshitting.
