This 100+ page internal report was not released until the 1990s. It is an internal report on Oswald's
foreign activities and the possibility of a foreign conspiracy in the assassination. Warren Commission staff
members William Coleman and David Slawson had generally focused in this area, and took a trip to Mexico City
in April 1964 to meet with CIA officers there (there is a separate report on that trip). Most of the focus
of this report is on possible Soviet involvement in the assassination, though there are shorter chapters
on Cuba and anti-Castro Cuban exiles.
