Ola's meeting was about moving Klingman out, not involving the Havana negotiations and Rocco was not at that meeting He was feeding Ola's men
Ola dispensed with moving Klingman out as a preliminary to actual meeting. Michael said to Ola: "Tom isn't gonna sit in with us -- he only handles specific areas of the family business" .When Tom says he'll be outside, Michael replies, "Just tell Rocco we're waiting." Ola didn't come that far West just to tell Michael that he could move Klingman out.
