Mr. Jenner. And did there come this occasion when Fredricksen spoke to you about the Oswalds one night?
Mr. Mamantov. That's right, and Fredricksen and his wife came to visit with us.
Mr. Jenner. Your home?
Mr. Mamantov. That's correct, and this was, I would say, sometime—March, April, might be of 1963, and so they told us yesterday or day before yesterday that they went to a very interesting party where the person present just came in from the Soviet Union and his wife, and the party was held at Glover's home. I asked him who was present. He said Mrs. Paine was present, of course, both Oswalds were present, and the De Mohrenschildts were present. Of course, Glover was present and I don't remember who else he mentioned, and we started the conversation.
Mr. Jenner. Was Fredricksen present?
Mr. Mamantov. Right, Fredricksen and his wife, he and my wife, my mother-in-law and myself violently jumped into the conversation, and I said, "Folks, you just don't know with whom you are associating. You shouldn't be at that party, and you shouldn't be going into those houses," and, of course, they said, "We just wanted to speak Russian. Mrs. Paine wanted to learn Russian, so we wanted to learn Russian and we just decided to get together and learn Russian." And they didn't speak Russian very much except with Marina. She was very shy and didn't talk very much. Most of the evening was spent conversing with Oswald on political questions, because he understood.
Mr. Jenner. This was the report they made to you?
Mr. Mamantov. That's correct.
Mr. Jenner. In the questioning by the Federal Bureau of Investigation, you mentioned either a Mr. Clark or a Mrs. Clark.
Mr. Mamantov. Yes, those people from Fort Worth.
