Who enforces the laws passed by Congress?

The President is responsible for enforcing the laws passed by Congress. This role is established by the U.S. Constitution, particularly in Article II, which outlines the executive branch's responsibilities. As the head of the executive branch, the President ensures that federal laws are implemented and followed. This includes overseeing federal agencies and departments, which carry out the specific tasks associated with enforcing these laws.

The other options represent different branches or levels of government. The Supreme Court interprets laws and can determine their constitutionality, but it does not enforce them. Senators are part of the legislative branch and are primarily involved in creating laws, not enforcing them. Governors operate at the state level and enforce state laws, not federal laws passed by Congress. Hence, the President is the ultimate authority for the enforcement of federal legislation.
