Paraphrasing the Director of the FBI, former Secretary H. Clinton was extremely careless in handling classified material, transmitting and placing many emails, classified at the TS/SAP level on unclassified personal systems, and across adversarial transmission systems.
The DoS guidelines clearly state disqualifying conditions: collecting/storing classified information in any unauthorized location; storing, transmitting classified information on any unapproved equipment; any failure to comply with rules for the protection of classified information.
Secretary H. Clinton's violated sufficient DoS Guidelines for revocation of a Security Clearance, and denial of access to classified material.
