<h3><u>What are Expressed powers?</u></h3>
Congress has been given the authority to carry out governmental functions through the Expressed Powers, sometimes referred to as Enumerated Powers.

These powers (also known as Clauses) are significant to how our Congress operates since the Tenth Amendment restricts Congress's authority to that stated in the Constitution.
The express powers include the ability to:

- assemble and maintain armed forces;
- establish standards of weights and measures;
- issue patents and copyrights;
- manage foreign affairs, and
