DEFUND Act of 2025

This bill mandates the complete withdrawal of the United States from the United Nations and all its associated organs, specialized agencies, and commissions. It requires the President to terminate all U.S. membership , repealing the United Nations Participation Act of 1945 and closing the U.S. Mission to the UN. The legislation also repeals the United Nations Headquarters Agreement Act, withdrawing the U.S. from the agreement regarding the UN headquarters. The bill prohibits all U.S. assessed or voluntary financial contributions to the UN, except for termination-related expenses, and forbids United States participation in any United Nations peacekeeping operations . It further stipulates that the UN may not occupy or use any U.S. Government property and revokes diplomatic immunity for UN officers, employees, and foreign mission representatives to the UN, nullifying relevant international agreements. This comprehensive disengagement extends to repealing the joint resolution for U.S. participation in the World Health Organization and ending U.S. involvement in all conventions and agreements with the United Nations and its affiliated bodies. For any potential future reentry into the United Nations, the legislation imposes strict conditions, requiring the advice and consent of the Senate for membership agreements. Such agreements must also include a reservation preserving the United States' right to withdraw, with the Secretary of State tasked to notify the UN of these provisions.
