A FBI report released on this day will mention: “The FBI investigation determined Clinton contributed to discussions in four email chains classified as ‘confidential’, three email chains classified as ‘secret’/NOFORN, and four email chains classified as ‘top secret’/ SAP.” (“SAP” stands for “Special Access Programs.”)
However, FBI classification is wildly different from State Department classification when it comes to “confidential” emails, with the FBI deeming 36 email chains of around 100 emails or less classified at that level, compared to the State Department deeming 2,028 individual emails classified at that level.
Furthermore, the FBI puts emails where Clinton asked aides to print out emails as different from replies that added to discussions. The FBI identified 67 times where Clinton forwarded emails for printing at either the “confidential” or “secret” levels. (Federal Bureau of Investigation, 9/2/2016)
By contrast, a March 2016 Washington Post analysis concluded that 104 of all the emails deemed classified were written by Clinton. Presumably, they used the State Department definition of which ones were classified (since it was the only one publicly available at the time), and they were measuring individual emails instead of email chains. Furthermore, the Post noted that at least some of Clinton’s comments were deemed classified in three-fourths of these 104 emails, so presumably these were not emails where she just asked fo print-outs.
