Final answer:
The expressed powers of Congress are enumerated in Article I, Section 8 of the U.S Constitution, granting legislative authority over various aspects of national and foreign policy.
Step-by-step explanation:
The expressed powers of Congress are listed in Article I, Section 8 of the U.S Constitution. These are the powers specifically given to the legislative branch of the national government, also known as enumerated powers. They provide Congress with a significant amount of authority over both foreign and domestic policy and include the power to levy taxes, regulate commerce, declare war, maintain an army and navy, and coin money, among other responsibilities. By listing these powers, the framers of the Constitution aimed to avoid the problems that had occurred under the Articles of Confederation by clearly delineating the powers of the federal government.
In addition to these expressed powers, there are also implied powers derived from the 'necessary and proper clause' discussed in the same section of the Constitution. These powers allow Congress to pass laws deemed essential for the execution of its enumerated powers. Amendment X, part of the Bill of Rights, further clarifies the division of power by reserving to the states or to the people all the powers not specifically granted to the federal government.
