IIRC, right before the gap he talks about the burlgars being cuban, and how if it gets out it could “blow the whole Cuban thing” or something to that affect.
I always wondered if he was referring to the Bay of Pigs, as I believe the Cuban guys in the break-in were involved with Kennedy and the Bay of Pigs.
The whole break-in was Dean’s business anyway - may he rot in hell someday. (From the excellent book “Silent Coup”).
