As for his "anti-Semitism": re his saying, "A Jew running the FBI?" What did he mean by that? Did he mean, many people might have issues with it, or did he mean, I will not permit it?
I guess it has something to do with the Rosenbergs, the establishment of a Zionist state, and the Zionist movement in this country. He saw a contingent of Jews, evidently, as proZionist and as such possible security risks (as has been borne out recently).
