This bill addresses the costs of renaming the Department of Defense to the "Department of War" by requiring those expenses to be paid from existing travel budgets rather than new appropriations. Specifically, the Secretary of Defense must cover all costs—such as updating signage, websites, stationery, and digital materials—by reallocating the department's travel funds, with the military departments' travel budgets serving as a secondary funding source if needed. The bill asserts that only Congress has the authority to change the department's name, since Congress originally established it by law. The Secretary must report to Congress within one year on the total amount spent on this renaming effort.
