It is not relevant because only one former Secretary had a private email account. It was done through a commercial server, gmail, authorized by the State Department and secured by the appropriate government agencies. Powell received two emails that were classified confidential last year. No one had a private email server in their home. That is the sum total of other secretaries with private email accounts. Hillary's private server was not authorized by the State Department or secured by any government agency. Hillary's email also had over 2100 classified emails with 110 that were classified at the time they were sent or received. More 20 were classified Top Secret and above. She claims that all work related emails were turned over but there were thousands of emails found that had not been turned over. These were found on other peoples email accounts, both govt. and private. Makes you wonder about those  supposedly private emails that were not turned over, just deleted?
