She has a drivers license too, so what?
You really think the first thing a spy who wants to use radio to communicate covertly is going to do is obtain a license from the federal government, announcing her intentions in federal documents accessible to anyone with Google?
Coincidence is not correlation.
Hillary was a shoo-in to win. Nobody expected Trump to win. None of this would have ever been known if Hillary had won. Nellie got the ham operator license because she knew that NSA doesn’t capture these communications. Why else would she get the license? Occam’s razor.
