“State Department, ‘Travel Regulations,’ December 13, 1963. Two State Department officers, legal advisor Abram Chayes and Abba Schwartz summarize [Robert F.] Kennedy’s arguments that ‘the ban on travel to Cuba be removed immediately,’ including that ‘the present travel restrictions are inconsistent with traditional American liberties.’ They note that lifting restrictions to Cuba is likely to be undertaken in the context of lifting most travel restrictions to other nations. They support Kennedy’s proposal but favor passport validation which would require those who travel to apply for permission from the Secretary of State to go to Cuba.” [Con Embargo]
