Answer:
The executive branch mainly interprets the federal laws and upholds or negates them.
Step-by-step explanation:
The U.S. government is based on the system of separation of powers (The executive, the legislative and the judicial). To interpret the federal laws and uphold or negate them is part of the Judicial duties, not the Executive.
Instead, the Executive branch is responsible for enforcing the laws. To accomplish such duty, it has 15 executive divisions or departments that are granted specific tasks and a specific budget each year to carry out the task.
Likewise, the President is also known as the chief of state as it officially represents the nation and performs ceremonial duties around the countries and he or she serves a term of four years at a time.
