What is the primary duty of the President of the United States?

The primary duty of the President of the United States is to enforce the laws. This responsibility is rooted in the role of the President as the head of the executive branch of the government, which is tasked with ensuring that federal laws are implemented and executed properly. The President appoints federal officials, including members of the Cabinet and heads of various departments, who help in the administration of these laws.

While making laws is traditionally the responsibility of Congress, and interpreting laws is primarily the role of the judiciary, the enforcement of laws falls squarely under the purview of the executive branch. The President also has significant influence over the direction of federal law through the issuance of executive orders, but these orders must align with existing laws and cannot create new laws.

The declaration of war, while an important power, is not solely the President's responsibility, as it requires Congressional approval. This division of powers signifies the checks and balances in place within the U.S. government, further emphasizing the essential role of the President in law enforcement rather than legislation or judicial interpretation.
