The POTUS using a pseudonym to communicate via email is hardly a scandal,
Most transparent administration evah!
The actual 'scandal', is that it seems Obama lied when he said he only found out about her email system through media reports (a way he has learned about many things).
more of an extra layer of security in case someone does get their hands on classified emails
Why would the President be emailing classified information on an unclassified system?

Bingo. No doubt former EPA chief "Richard Windsor" agrees.
It's even more silly in that Presidential records are generally not FOIAable or subpoenable, even when her SoS emails were being released.
