Mr. McCONE. Yes; we were aware that Oswald did make a trip to Mexico City and it was our judgment that he was there in the interest of insuring transit privileges and that he made contact with the Cuban Embassy while he was there. We do not know the precise results of his effort, but we assumed, because he returned to the United States, he was unsuccessful. We have examined to every extent we can, and using all resources available to us every aspect of his activity and we could not verify that he was there for any other purpose or that his trip to Mexico was in any way related to his later action in assassinating President Kennedy. Representative FORD. Did the Central Intelligence Agency make any investigation of any alleged connection between Oswald and the Castro government? Mr. McCONE. Yes; we investigated that in considerable detail, because information came to us through a third party that he had carried on a rather odd discussion with Cuban officials in the Cuban Embassy in Mexico City. The allegation was that he had received under rather odd circumstances a substantial amount of money in the Cuban Embassy, and the statement was made by one who claimed to have seen this transaction take place. After a very thorough and detailed examination of the informer, it finally turned out by the informer's own admission that the information was entirely erroneous, and was made for the purpose of advancing the informer's own standing with the Central Intelligence Agency and the U.S. Government and it was subsequently retracted by the informer in its entirety. Representative FORD. Was there any other evidence or alleged evidence---- Mr. McCONE. Parenthetically, I might add a word for the record that the date that the informer gave as to the date in time of this alleged transaction was impossible because through other, from other, information we determined that Oswald was in the United States at that particular time. Representative FORD. Did the Central Intelligence Agency ever make an investigation or did it ever check on Mr. Ruby's trip to Cuba or any connections he might have had with the Castro government? Mr. McCONE. Not to my knowledge. Mr. HELMS. We had no information. Mr. McCONE. We had no information. Representative FORD. Central Intelligence Agency has no information of any connections of Ruby to the Castro government? Mr. McCONE. That is right. Representative FORD. Did you ever make a check of that? Mr. HELMS. We checked our records to see if we had information and found we did not. Representative FORD. What would that indicate, the fact that you checked your records? Mr. HELMS. That would indicate that if we had received information from our own resources, that the Cubans were involved with Mr. Ruby in something which would be regarded as subversive, we would then have it in our files. But we received no such information, and I don't, by saying this, mean that he did not. I simply say we don't have any record of this.
