Seeing the actual documents is commonly better than reading about them, so I thought it might be valuable to see the CIA document that suggests Attorney General Robert Kennedy had agreed to meet with Rolando Cubela if necessary. Of course, this is a CIA document about its plan. It doesn't prove the Attorney General had agreed.
By way of background, on October 13, 1963, the CIA's Nestor Sanchez met with Cubela and Carlos Tepedino. At that meeting, Cubela said he wanted to meet personally with Robert Kennedy. And so Sanchez cabled CIA headquarters: "recommend [Cubela} be flown back by military aircraft to U.S. for for two or three days. Attempt arrange short meeting with [Robert Kennedy] or if this is not possible with other high official responsible for [Cuban] affairs."
Within an hour of receiving the cable, Desmond FitzGerald called Robert Kennedy. The phone record of that call is in an earlier blog entry of August 26, 2019. Ultimately though, the CIA decided instead to have Desmond FitzGerald fly to Paris and meet with Cubela under an alias as the personal representative of the Attorney General. The CIA document with the plans for that meeting is NARA 104-10102-10030. It is a three-page undated and apparently sanitized document. The first page is "Scenario" that describes the expected arrangements for the meeting, including an "impressive" safehouse under CIA control. The third page, labeled Fall Back, below, provides that if the FitzGerald meeting isn't enough, Cubela will be flown back to the United States to meet with another high government official. Although one might argue that this official might be Richard Helms or John McCone of the CIA, given that Cubela wanted to meet Robert Kennedy, there is little doubt that this was the CIA's fall back.
