This bill amends federal defense law to expand the authority of the Secretary of Defense to negotiate and enter into intergovernmental support agreements on behalf of Defense Agencies. Currently, the Secretary of Defense can make such agreements only for military departments, but this bill clarifies that the term "Secretary concerned" also includes the Secretary of Defense when acting on behalf of Defense Agency heads. These intergovernmental support agreements allow the Defense Department to coordinate with other federal, state, or local agencies to provide services and support. The change is administrative in nature and does not specify new funding or implementation timelines. The bill was introduced in October 2026 and referred to the House Committee on Armed Services.
