The main purpose of this legislation is to formally withdraw the United States from the World Health Organization (WHO) and to prohibit any federal funding for participation in the organization or any similar entities. This move reflects a desire among some lawmakers to limit international health governance and assert more national control over health policy. Key provisions of the legislation include a directive for the President to withdraw the U.S. from the WHO's constitution and a ban on using federal funds for any involvement with the WHO or its successor organizations.
