Which law gives the President authority to direct the Department of Defense to provide domestic aid for disasters?

• A. National Security Act
• B. Posse Comitatus Act
• C. The Stafford Act
• D. Homeland Security Act

Answer: (C)

The key idea here is which law specifically authorizes the President to call in federal resources, including the Department of Defense, to assist civilian authorities during disasters. The Stafford Act (Robert T. Stafford Disaster Relief and Emergency Assistance Act) provides the framework for federal disaster response. It allows the President to direct federal agencies to support state and local governments when a major disaster or emergency is declared, coordinating and supplying the necessary aid and military assets as needed. This authority is what enables DoD involvement in domestic disaster relief, under the President’s direction and in close coordination with civilian authorities, to supplement local capabilities and resources.

Other laws set up structure or impose limits but don’t grant this direct authority in the same way. The National Security Act reorganizes defense and intelligence functions; the Posse Comitatus Act limits the use of federal troops for law enforcement rather than disaster response; the Homeland Security Act creates DHS and coordinates civilian agencies. Thus, the Stafford Act is the statute that provides the authority for the President to direct the DoD in domestic disaster aid.
