What is the president's job?

The president's chief duty is to protect the Constitution and enforce the laws made by Congress. However, he also has a host of other responsibilities tied to his job description. They include: recommending legislation (laws) to Congress; calling special sessions of Congress; delivering messages to Congress; signing or vetoing legislation; appointing federal judges; appointing heads of federal departments and agencies and other principal federal officials; appointing representatives to foreign countries; carrying on official business with foreign nations; acting as commander in chief of the armed forces; and granting pardons for offenses against the United States.

A U.S. president is not all powerful, but as head of state he has great influence on the country. Some presidents, such as Abraham Lincoln, have been credited with changing the course of American history.
