Re: In this case it certainly wasn't illegal:
Quoting a story from flacks working for the DNC doesn't work in this case.
It's been illegal since she was too young to vote, specifically the Federal Records Preservation Act of 1950.
I work as a contractor in IT Support for the government. There simple truth is a high level politician CAN'T have a single email account and comply with all the laws governing the use of email and government equipment. You can't use official government accounts for fundraising. You can't use personal accounts to transmit government sensitive information. Anything that is a record MUST be preserved. The only way you can work all of this is with separate email accounts for each function, and the government one has to be on government equipment to meet discovery and preservation requirements.
