Robert F. Kennedy Jr. announced the reorganization on March 27, 2025, as an implementation of President
Donald Trump's
Executive Order 14210.|left The current overall organizational structure of HHS is the result of the
Public Health Service reorganizations of 1966–1973, as well as the 1980 spinoff of the
Department of Education which caused HHS to be renamed from its former name, Department of Health, Education, and Welfare. Since then there have been a few new operating agencies and minor reorganizations. The individual agencies within HHS draw their statutory authority from a patchwork of
authorization bills passed by Congress, and
administrative regulations instituted by the department or its agencies through the
federal rulemaking process. On one extreme, the
National Institutes of Health is authorized by the 1930
Ransdell Act and its subsequent amendments, which also specify all of its
constituent institutes and centers, meaning these can only be changed by an act of Congress. On the other extreme, the
Centers for Disease Control and Prevention is not directly established by any statute, but by departmental regulation that delegates to it some authorities of the umbrella 1944
Public Health Service Act as amended, although specific statutes exist for three of its component centers. After the
2024 presidential election and the beginning of the
second Trump administration,
Robert F. Kennedy Jr. was confirmed as
Secretary of Health and Human Services. On February 11, 2025, President Trump signed
Executive Order 14210, "Implementing the President's 'Department of Government Efficiency' Cost Efficiency Initiative". The order required large-scale
reductions in force in consultation with the
Department of Government Efficiency program, and submission of a reorganization plan by each agency to the
Office of Management and Budget within 30 days. == Provisions ==
