"The legal procedure through which the United States withdraws from treaties and other international agreements has been the subject of long-standing debate between the legislative and executive branches. Recently, questions concerning the role of Congress in the withdrawal process have arisen in response to statements made by President Donald J. Trump that he may consider withdrawing the United States from certain high-profile international commitments. This report outlines the legal framework for withdrawal from international agreements under domestic and international law, and it examines legal issues related to the potential termination of two agreements that may be of significance to the 115th Congress: the Paris Agreement on climate change and the Joint Comprehensive Plan of Action (JCPOA) related to Iran's nuclear program."
