Who is responsible for the execution of laws passed by Congress?

The President is responsible for the execution of laws passed by Congress due to the roles outlined in the U.S. Constitution. Specifically, Article II of the Constitution establishes the Executive Branch, which is headed by the President. This branch is charged with enforcing laws and administering the various functions of government.

When Congress enacts legislation, it is the President's duty to ensure that those laws are implemented effectively. The President works with various federal agencies and departments to carry out this mandate, overseeing the enforcement of laws in areas such as environmental regulations, immigration, and taxation.

In contrast, the other entities mentioned have different roles: Congress creates laws, while the Supreme Court interprets them to ensure they align with the Constitution. The Vice President assists the President but does not hold the primary responsibility for law enforcement.
