Why is it important whether they were told or not?
From the article:
“A law enforcement official said on Sunday that in the investigation that led to the indictment of Mr. Kim, ‘the government issued subpoenas for toll records for five phone numbers associated with the media.’ This person, who spoke on the condition of anonymity, added, ‘Consistent with Department of Justice policies and procedures, the government provided notification of those subpoenas nearly three years ago by certified mail, facsimile and e-mail.’”
The law required Holder’s DOJ to make the above notification to News Corp. News Corp says they never got it.
