AGENCY FOR INTERNATIONAL DEVELOPMENT ET AL. v. ALLIANCE FOR OPEN SOCIETY INTERNATIONAL, INC.

JUSTICE KAVANAUGH delivered the opinion of the Court. In 2003, Congress passed and President George W. Bush signed the United States Leadership Against HIV/AIDS, Tuberculosis, and Malaria Act, known as the Leadership Act. 117 Stat. 711, as amended, 22 U. S. C. §7601 et seq. Aiming to enhance America’s response to the ravages of the global HIV/AIDS crisis, the Leadership Act launched “the largest international public health program of its kind ever created.” §7601(29). The Act has helped save an estimated 17 million lives, primarily in Africa, and is widely viewed as the most successful American foreign aid program since the Marshall Plan.
