TLS, one page, 8 x 10.5, FBI letterhead, April 11, 1967. Response to a citizen. In part: “The over-all substance of my testimony before the House Subcommittee on Appropriations…was that an increase in the number of Soviet-bloc personnel in the United States enlarges in direct proportion the problem of maintaining our internal security…I do not inject the FBI or myself into legislative matters, comment on specific court decisions, or make recommendations…I am unable to make any statement pertaining to your question on Administration programs, Supreme Court decisions, or the John Birch Society and Young Americans for Freedom. You might like to know, however, the FBI has not investigated either of the organizations you named.” In fine condition, with some subtle toning. RR Auction COA.
