What is an example of an expressed power of the federal government?

The expressed powers of the federal government are specifically listed in the U.S. Constitution, primarily in Article I. One of the most significant expressed powers is the authority to declare war. This power allows the federal government to engage in military conflict and manage national defense, making it a crucial responsibility for the country's sovereignty and security.

Establishing public schools and conducting elections are typically power reserved for state and local governments rather than the federal government. Similarly, conducting local government functions falls under the jurisdiction of state and local entities, as they manage their own governance structures independently. Thus, declaring war stands out as a clear example of an expressed power assigned to the federal government.
