she blatantly violated State Department rules by handling all of her emails on a private server (not even a private address, she set up her own server ran out of her apartment so that it would be even harder for the public to see her messages)
State Department rules she wrote herself and were not in place under her predecessors.
Aren't strict constitutionalists like yourself complaining about the executive branch writing their own laws?
If Congress is concerned about cabinet members using government email addresses, they should pass a law about it.
