Monday/ hillary@yahoo.com?

It was revealed today by a report in the New York Times that the presumptive 2016 Democratic nominee for President – Hillary Clinton – used a personal e-mail account throughout her entire tenure at the State Department as Secretary of State.   This raises many questions.  1. Why?  It’s sort of against the law.  2. Was the e-mail account secure?  I am not even allowed to send work e-mail outside our encrypted e-mail system.  And I don’t deal with state secrets.  3.  Why has this not been raised before? By her aides, her advisors, by people receiving her e-mail.   4.  Will this turn into a scandal that undermine her (as-yet-unannounced) bid for the White House in 2016 ?  5. What I want to know most of all : what was the account’s name?  Presumably more formal than hillary@yahoo.com, right?
