LOL policy issues? Only a partisan Whack-A-Doodle thinks that, thus EDN. It's against a myriad of Federal Laws to conduckt Federal business over a not Federally operated IT system. Everyone with a clue (thus, not EDN) knows she was hacked, and probably hacked by just about every intelligence entity and bad guy with an Internet connection.
I guess if you're trying to launder money and sell access through your fake foundation, running a private email server does make sense.
