“December 12 [1963]. Less than one month after President John F. Kennedy’s assassination, U.S. Attorney General Robert F. Kennedy seeks to end the travel ban to Cuba in a memo to Secretary of State Dean Rusk. He refers to the ban as ‘inconsistent with traditional American liberties,’ and difficult to enforce. The memo is not released to the public until June 29 2005.” [Con Embargo]
