Did Colin Powell really say that? Maybe a link - I'd love to hear it!
Basically yes, it was in a hacked email that was published. Powell is pissed, he said it was a big advantage for him to use his private email account for non classified communications and Hillary has forever ruined that for future SOS's by being a fucktard and setting up her own unsecure server and not using the government email for classified stuff. He then said out of frustration that as long as he's known her this is what she does, she screws up everything she touches, she's a moron basically.
