Hello! I am looking for Dept. of State records pertaining to the U.S. negotiation of the 1967 refugee protocol, from the years 1965 (when the draft protocol was circulated) to 1968 (when the U.S. signed the treaty). At the moment, I am trying to locate two memorandums that were sent by Ambassador Graham Martin, Special Assistant to the Secretary of State for Refugee and Migration Affairs, to the Department of Health, Education and Welfare in July 1968. I would appreciate any leads or recommendations! Thank you so much
