That would be blackmail, but then the argument against felony clinton all along has been that her negligent use of email could ar has made her susceptible to blackmail.
Usually black mail is a private warning. And usually it’s a trade. If wikileaks had sent her a secret message asking for money or for Julian being pardoned or some other favor, that would be black mail. I am nother sure this story is true, but if it is its actually a noble gesture rather than black mail.
