Well, your Politifact link completely supports what I said, so.......
If you are seriously arguing semantics, that I suggested "making an email server" is illegal rather than "setting up an email server with the intent of transmitting Government work and/or classified information so as to avoid detection and logging and in the process operated outside of the security of a government network" is illegal, then, well you win. Well done.She didn't because it wasn't against the law. There may be things that happened with that email server later that were against the law, but the very premise was wrong. Just like how the actual collusion itself is not against the law, but things related to it may very well be.
Edit: Or for clarity "using an existing server with the intent of transmitting Government work and/or classified information so as to avoid detection and logging and in the process operated outside of the security of a government network" is illegal
The point being the discussion is about what she did with an email server, not that email servers legally exist. I think we can all agree email servers exist legally.
