Mr. HOOVER. We have had no credible evidence that they have been related to the Communist Party in this country. Now, as to Mrs. Oswald, the wife of Oswald, there is no way of knowing whether she belonged to the Russian Communist Party in Russia. She is a rather intelligent woman, and notwithstanding that you have to talk with her through an interpreter, we have had no indication of her association with Communists in this country, nor have any of her close friends or relatives. As to his mother, we found no indication she is associated or closely associated with the Communists. She is the only one of the group that we have come in contact with that I would say is somewhat emotionally unstable. Our agents have interviewed her. She sometimes gets very angry and she won't answer questions. As to the rest of the group who had been friends of his, or worked with him in the Texas School Book Depository, none of them have indicated any Communist associations of any kind. Senator COOPER. Thank you. Mr. HOOVER. Thank you. Mr. RANKIN. Mr. Hoover, I hand you Exhibit 863 and ask you to examine that and state whether or not that is the letter that you referred to in which you answered questions of the Commission concerning the National Enquirer magazine or newspaper? Mr. HOOVER. This letter of May 8 addressed to the Commission is the letter that dealt with our interview with Chief Curry and was predicated upon the article which appeared in the National Enquirer of May 17, 1964. Mr. RANKIN. I ask you if you would care to add anything to that letter except what you have already testified to? Mr. HOOVER. No; I have nothing to add to that. Chief Curry was very specific, I am told by my agent in charge at Dallas, that this article is an absolute lie; that none of these things set forth in the article occurred; that he received no phone call or any request of any kind oral or by phone or in writing from the Department of Justice or from the FBI. As I stated earlier, the report from the Department of Justice indicated that they made no request. Mr. RANKIN. Mr. Chairman, I offer in evidence Exhibit 863, being the letter just referred to. The CHAIRMAN. It may be admitted. (The document referred to was marked Commission Exhibit No. 863 for identification and received in evidence.) Mr. RANKIN. Mr. Hoover, is Exhibit 837 the article that you referred to in the National Enquirer? Mr. HOOVER. Yes; that is the one. Mr. RANKIN. I call your attention to Exhibit 836 and ask you if that is the letter that you referred to which describes the criteria in the handling of the security of the President that you have described in your testimony. Mr. HOOVER. This is the letter. It sets forth the criteria which were adopted, originally about 1942 and later incorporated in the manual of instructions in 1954. It also includes the amended instructions to our field offices, prepared in December of 1963, which extended the criteria.
