I think it could possibly be the only reason Hillary would use her personal e-mail at work instead of the State Dept. e-mail. She probably didn’t want confidential information about certain stuff to get on the State Dept. archives. Using personal e-mail would be easier to cover up her crimes more ’cause she can delete things faster. Like private conversations with Barack Obama and State Dept. officials. If she used the State Dept. e-mail, they’ll be able to read everything she’s writing and if she’s caught discussing anything criminal… well….
