State Department legislative liaison Julia Frifield sends a letter to the Senate indicating an apparent change in what information the State Department considers properly classified. The vast majority of redactions in Clinton’s emails are for foreign government information, to which Frifield refers as “FGI.”
Frifield writes, “Although the unauthorized release of FGI is presumed to cause harm to the national security—thereby qualifying as Confidential [level] classified information, department officials of necessity routinely receive such information through unclassified channels. For example, diplomats engage in meetings with counterparts in open settings, have phone calls with foreign contacts over unsecure lines, and email with and about foreign counterparts via unclassified systems. Diplomats could not conduct diplomacy if doing so violated the law.” As a result, not all such information should automatically be considered classified.
However, regulations in effect when Clinton was secretary of state called for FGI to be marked “confidential” unless it was designated “C/MOD” (for “confidential/modified handling”). But none of Clinton’s emails appear to have been given that designation. (Politico, 5/12/2016)
