My ex husband is in the Army and has top secret clearance. He hacked into my "new" husband's gmail in order to defame him at work. Who do I report this to?

Use the Report a Crime email address so your complaint is documented in writing and ask for an acknowledgment in your email.
Make sure you attach documentation from your husband's gmail account to support your complaint.
I think it would be better if your husband sent the complaint since the crime was committed against him.
