Why is the exposing of a government employee's email address a security risk to you?
Edit, because downvotes: government email addresses can be retrieved easily through public records laws, and is done routinely, and can easily be scraped or inferred. I've done both many, many times, and it's trivial.
Well at the very least it presents a soft target for hacking into his personal email adddress (it's gmail not govenrment) and secondly, compromising it literally gives you access to dial into cabinet meetings.
And like one of the other comments in this chain points out - his personal email address was being used for government affairs, and that made it open to public records law suits. The public already has access to it.
