President Trump signs executive order 14199, directing all federal agencies to exit 66 international organizations, including the Global Counterterrorism Forum; the U.N. Framework Convention on Climate Change; the Intergovernmental Panel on Climate Change; the Intergovernmental Forum on Mining, Minerals, Metals, and Sustainable Development; and the U.N. Office of the Special Representative of the Secretary General for Children in Armed Conflict.
