"The President of the United States of America can personally call"
I think Barrack Obama can make a personal call but The President of the US can't.
When an email comes from @state.gov with the description of "U.S. Department of State SUBJECT TO AGREEMENT ON SENSITIVE INFORMATION & REDACTIONS." I don't think it can be considered Hillary making a personal request.
Ironically this might have been a very appropriate use of Clinton mail.
