Who, if any, in JFK's inner circle argued against the plans for the Bay of Pigs invasion?

Question

Political discussions leading up to the Bay of Pigs invasion are a notorious example of 'groupthink' and the failure of a committee in coming to a well-informed decision. Accounts of the decision-making process of JFK's inner circle include poor communication and various group pressures/fumbles on the part of the committee.

Given this, of JFK's critical advisers, did anyone speak out (publicly or privately) against the planned Bay of Pigs invasion either in principle or out of tactical concern?

Answer 1

Apparently, Arthur Schlesinger wrote a memo against the "upcoming" Bay of Pigs idea. But he didn't push it very hard.
