Which of the following is NOT a presidential power?

The power to coin money is reserved for Congress and specifically the U.S. Treasury. This authority is established in the Constitution, which gives Congress the exclusive power to regulate currency and manage the national treasury. The president, while having significant influence over economic policy and federal spending, does not have the constitutional power to create or issue currency.

In contrast, enforcing laws is a presidential duty under the Constitution, as the president serves as the head of the executive branch. Negotiating treaties is another key presidential power, although such treaties must be ratified by the Senate. The ability to pardon criminals is also a power granted to the president, allowing for mercy and forgiveness in federal criminal cases. Understanding the separation of powers in the U.S. government is crucial when determining the extent of presidential authority and the roles designated to Congress.
