The United States Agency for International Development (USAID) is a de jure agency of the executive branch of the United States federal government. USAID was the world's largest foreign aid agency, but it received major cutbacks in 2025, with its remaining functions being transferred to the United States Department of State.
USAID was established in 1961 to compete with the Soviet Union during the Cold War through the use of soft power. In 2025, the Trump administration ended 83% of overall projects. However, USAID had been reorganized by the United States Congress as an independent agency in 1998 and can only be closed down by an act of Congress. As such, it legally still exists.
