- During World War II, all had been lovers of Pamela Churchill.
- The KGB had kompromat on all of these men and tried to blackmail them with it.
- All sang on the Yale Glee Club together.
- All were the basis for characters in the “La Côte Basque” chapter of Truman Capote’s scandalous unfinished novel, Answered Prayers.
If the KGB had kompromat or attempted to blackmail any of these men, it remains undisclosed. Given that Averell Harriman was President Harry Truman's Ambassador to the Soviet Union and Dean Acheson was his Secretary of State, the Soviets have have been thrilled to have compromising information on either.
Lastly, Cole Porter appeared in "La Côte Basque" and Truman Capote did not even bother to disguise his name.” It is also possible that Averell Harriman is the governor referenced in that chapter, but others believe it to be Nelson Rockefeller.
