Answer:
Based on the responsibility of being head of the executive branch, the president must carry out the laws of the nation .
Explanation:
The president as the head of the executive branch must observe, apply and enforce the country´s laws. It´s one of his duties. He can´t exercise a power that his office has not been vested with. The executive branch doesn´t create laws; that´s the role of Congress stipulated by the Constitution. The president can´t also interpret the law; it´s the role of the judiciary, the judicial branch.
