If only things were that simple. The book, The Whistleblower by Marinka Peschmann, 2011, has a good narrative at all the tricks invented by the Clintons, and perfected by Hussein, to evade the transparency they both shouted from the rooftops, pounding their chests ( except, perhaps, Hillary).
Using private computers on clearly national interest matters, to evade the recordkeeping required by law, is a good example.
Even if they are, I'll wager the date still exists. All that's required is the will stop asking for it, and go take it.
