The President of the United States is in charge of the entire federal government as the head of the executive branch. The Founding Fathers, in the 1776 Declaration of Independence from Great Britain, stated that "all men are created equal." This guiding principle of equality directed the founders to establish a government of three co-equal branches, with checks and balances in place to prevent one branch from acquiring too much power.
The President's Powers
The U.S. president is the head of government and the commander-in-chief of the armed forces. The president is empowered by the Constitution to implement and enforce all congressional laws. The president appoints the heads of the various federal departments. When both houses of Congress -- the House of Representatives and the Senate -- approve the same bill, that legislation is sent to the president for his signature. With the president's signature, the bill becomes law. However, if he vetoes the bill, that veto can be overturned if two-thirds of the House and Senate vote to approve the bill. The president nominates people to the judicial branch, but these candidates must be confirmed by the Senate.
