From Pg 217 of FBI 33 of 33 drop today. Redacted but refers to 2013 American Foreign Service Speech on video: FBI wanting context.
Is it referring to this 2013 vid from Kerry or other related clips regarding Ambassador Chris Stevens and other victims of Benghazi? Biden as VP in attendance. CFR and other info mentioned in speech about victims.
Perhaps another speech altogether, but looks like FBI wanted more info about something in the video referenced.
