The FBI concluded their investigation into Secretary Hillary Clinton's private e-mail server. The Director of the FBI called her "extremely careless" with classified information. She either didn't know or lied about sending classified information; either one is unacceptable for ANYONE with access to classified material.
Not suspending her clearance and access to classified documents for life sets a terrible precedent. Unless we are planning to exonerate those (mil/civilian/et al) who have made the same mistake.
The greatest asset to our country are its people. She endangered that asset by doing the easy wrong instead of the harder right; which shows a lack of moral courage. Doing what is convenient instead of the right thing is something President Obama has emplored us all to not do.
