Proof from Halper’s Institute of World Politics:
Stefan Halper is a “Career Incumbent” SES employee (proof the SES is hiding Halper’s SES Career Incumbent association with SES)
Stefan Halper. (Accessed May 20, 2018). Faculty Biography. The Institute of World Politics.
Plum Book 1984, p.145 – Stefan Halper = “…..do…….“ = Career Incumbent
This entry does not identify the name of the person, but instead indicates that the identity is “do”. “Do” presumably means Ditto, although it is not defined. In this context it means a “Career Incumbent”
