Mr. JOHNSON. Very simply that as an American citizen, whatever he is doing should always be aboveground; that a person remains in the background within any organizational activities, that he does not push himself forward in whatever he is doing. (Document marked Johnson Exhibit No. 5.) Mr. RANKIN. I hand you Exhibit No. 5 and ask you whether that letter dated August 31, 1963, consisting of two pages and an envelope, was one of the pieces of correspondence you turned over to the FBI at the time you described? Mr. JOHNSON. It is. Mr. RANKIN. Had you seen that Exhibit 5 at some time prior to the time you turned it over? Mr. JOHNSON. Oh, yes; just within a couple of days before, I think it was. Mr. RANKIN. It is addressed to a Mr. or M. Bert. I guess Mr. Bert. Mr. JOHNSON. Mr. Bert. Mr. RANKIN. Can you tell us who that is? Mr. JOHNSON. He is the managing editor of the Worker. Mr. RANKIN. How did that Exhibit 5 come to your attention? Mr. JOHNSON. I inquired specifically of the Worker as to whether there was any other correspondence when I was assembling the material to turn over, and I insisted upon a search of files, in an easy way, "Please look through the files and see if there is anything." Mr. RANKIN. Who did you make that inquiry of? Mr. JOHNSON. I made that actually to Mr. Jackson. Mr. RANKIN. Can you tell us who Mr. Jackson is, enough so that we can know how he may be acting or he may have the authority to search the files? Mr. JOHNSON. He is the editor of the Worker. Mr. RANKIN. That was done shortly before you turned over the other papers and this to the FBI? Mr. JOHNSON. Yes. Mr. RANKIN. Do you have any basis for believing that when you made such a request it would be carried out? Mr. JOHNSON. Oh, yes. Mr. RANKIN. Can you tell us enough about that so we would know what reason you would have to believe that it would be carried out? Mr. JOHNSON. Well, the relationship would be one, which was very normal; the editorial policy of the Worker in relationship to the assassination; and insistence upon cooperation in any fashion to determine anything related to it that would be helpful in the work of the Commission or Government agencies involved. There was no resistance, and there was immediately a willingness and desire to do so; that is all. Mr. RANKIN. Did you ask that there be a complete search for anything that would show any correspondence? Mr. JOHNSON. I did. Mr. RANKIN. Or contact with Lee Harvey Oswald by either the Communist Party in the United States or the Worker? Mr. JOHNSON. I did. Mr. RANKIN. Are you satisfied that that search was full and complete? Mr. JOHNSON. Yes; I am. Mr. RANKIN. And that whatever you turned over to the FBI was all that either of those organizations had in their possession? Mr. JOHNSON. That is correct. Mr. RANKIN. Did you have any further conversation with Mr. Bert in regard to Lee Harvey Oswald?
