What federal legislative steps are required to change a cabinet department's name and what are the estimated administrative costs?
Executive summary
Changing the name of a federal cabinet department requires congressional action to amend statute in most cases, because department titles and many authorities are written into federal law — though a President can issue executive orders to use alternate or secondary titles while seeking Congress’ approval (see White House executive order directing recommendations and Congress’ role) [1] [2]. Media and congressional staff estimates place administrative and rebranding costs for a major department rename in the low billions — NBC News and other outlets reported estimates up to about $2 billion for renaming the Department of Defense — driven by signage, emblems, treaties, websites and personnel records [3] [4] [5].
1. What the law says: Congress usually controls department names
Congress has “plenary authority” over the creation and statutory structure of federal agencies and departments; names and legal authorities for executive departments are embedded in federal statutes, so making a permanent change generally requires Congress to pass legislation amending those statutes [6] [2]. Executive actions can direct agencies to use alternate or “secondary” titles and to prepare legislative recommendations, but those orders do not by themselves rewrite federal law — the White House order that sought to restore the “Department of War” specifically directed the secretary to propose the legislative steps needed and acknowledged Congress would still need to update federal law [1] [2].
2. How an administration can act immediately — and its limits
An administration can issue an executive order to change internal usage, apply a secondary title, or reorganize certain functions under existing statutory authority; the 2025 White House order used a “secondary title” approach and instructed the department to recommend legislation to make the change permanent, illustrating executive orders’ ability to initiate but not finalize renaming [1] [4]. Congressional committees, the Office of Management and Budget, and interagency reviews will typically be consulted for downstream impacts before any durable statutory change proceeds [1] [6].
3. Typical legislative steps Congress would take
Available sources describe the general path: the administration or members of Congress would introduce a bill (for example, a “Restoration Act”) to amend the statutory name and related provisions; committees with jurisdiction (e.g., Armed Services, Appropriations) would hold hearings and markups; if passed by both chambers, the bill would go to the President to be signed into law — this is the conventional route implied by reporting on members introducing bills to make renaming “permanent” [7] [1]. The Congressional Budget Office (CBO) may be asked for a cost estimate to inform lawmakers, as Senate Democrats requested CBO input on renaming impacts [3].
4. Administrative and compliance tasks driving cost
Reporting on the Pentagon renaming outlines concrete cost drivers: replacing signage and emblems at hundreds of sites, redesigning logos and stationery, updating websites, digital infrastructure, personnel records and badges, reissuing treaties or updating references in intergovernmental agreements, and changing manuals and uniforms — a set of tasks that scales with department size and global footprint [3] [4] [8]. Media and congressional staffers told NBC that the cumulative effect of these items could reach about $2 billion for the Defense-to-War renaming scenario; other outlets and analysts likewise expected a billion-dollar-class price tag for a similarly large department [3] [4] [5] [9].
5. What influences the size of the price tag
Available reporting points to department scale ($842 billion budget and millions of personnel cited when discussing DoD), the number of facilities, overseas partners and treaties that reference the department, IT and cybersecurity updates, and the need to reprint or reissue legal and operational documents as key multipliers of cost [9] [3] [4]. The CBO had not provided a formal score at the time of reporting for some proposals, underscoring uncertainty and the potential for wide variance in estimates [7] [3].
6. Disagreements and political framing to watch
Proponents framed renaming as symbolic restoration of tradition and a matter of messaging; critics and some former officials called it wasteful and an “administrative nightmare,” emphasizing cost and operational disruption [7] [10]. Several media outlets reported similar cost estimates and highlighted that the White House’s executive action alone would not complete a statutory renaming, illustrating cross-branch tensions between presidential initiatives and Congressional authority [1] [3] [4].
7. Limitations of current reporting and next steps for readers
Available sources do not provide a single definitive legal checklist or line-item federal cost accounting; estimates are media- and staff-sourced and CBO scoring was not always available at the time of reporting [3] [7]. For a precise legal path and authoritative cost estimate in any specific renaming case, readers should consult the actual bill text, formal CBO estimates, and legal counsel or OMB analyses — these specific documents are not included in the current reporting (not found in current reporting).
