The main function of the President of the United States is to enforce laws. This responsibility is rooted in the Constitution, which designates the President as the head of the executive branch of the federal government. This role includes ensuring that laws are implemented properly and effectively, overseeing the various departments and agencies that carry out governmental functions, and making sure that federal laws are upheld.

The President’s enforcement powers extend to a range of actions, such as issuing executive orders, appointing federal officials, and directing law enforcement and national defense initiatives. This central role in law enforcement differentiates the President's responsibilities from those of Congress, which is tasked with making laws, and the judiciary, which interprets them. Thus, the primary emphasis of the President's job lies in the enforcement of federal laws and the administration of public policy.
