“June 29 [2005]. The National Security Archive releases a memo written by Attorney General Robert F. Kennedy on December 12 1963 (less than a month after President [John F.] Kennedy’s assassination), in which he seeks to lift the travel ban to Cuba. He refers to the ban as ‘inconsistent with traditional American liberties.’ Also released is a memo about a December 13 1963 meeting at the State Department (to which Kennedy was not invited), in which Undersecretary of State George Ball rules out the possibility of ending the travel ban.” [Pro Embargo] [Con Embargo]
