Who enforces laws in the United States?

The enforcement of laws in the United States primarily falls under the role of the President. The President is responsible for ensuring that federal laws are executed faithfully, which includes overseeing federal law enforcement agencies, such as the FBI, and managing the executive branch of government. This role is established by the Constitution, which grants the President the authority to enforce laws passed by Congress.

While Congress makes the laws and the judiciary interprets them, the practical enforcement of those laws is a function of the executive branch, led by the President. The Supreme Court, while important in interpreting laws and settling legal disputes, does not have a role in law enforcement. Similarly, state governors enforce state laws within their jurisdictions, but when the question pertains to the overall enforcement of laws in the entire country, the President is the primary figure in that role.

Thus, the chosen answer reflects the correct understanding of the functions of the branches of government, particularly emphasizing the executive branch's responsibility regarding law enforcement.
