The United States Constitution provides for National Government three separate branches -- executive, legislative, and judicial -- each with its own special powers and duties. Separation of powers and duties among the branches enabled them to check and balance each other and balance the authority of other two.

             The Executive Branch is the President who was made Commander-in-Chief of all the nation's armed forces. Also president has a power to sign bills into laws, negotiate peace treaties, and to appoint officials. However to check and balance his power, for example the Senate (Legislative Branch) had to approve President's peace treaties by two-thirds majority of all senators present. Also some of his choices of appointed officials, such as justices of the Supreme Court (Judicial Branch) and ambassadors to foreign lands, had to be approved by the Senate (Legislative Branch). The Executive Branch has not power of creating the laws by themselves and making them legal. Legislative Branch has to make decide on the particular law and if it satisfies everyone and nobody has anything against it, then that bill is given to the President to be signed so it'll be legal. Executive Branch controls and checks that the Legislative Branch wouldn't pass any law they just make up, because it would be an abuse of power (because they will be able to do whatever they want) so they have the final word on if it'll be legal or it won't be signed, therefore wouldn't be legal. The Judicial Branch will decide if the law is constitutional or unconstitutional so no illegal laws would be in power and abuse of power won't occur.

             Legislative Branch consists of Congress, House of Representatives, and Senate. Each house of Congress was given special powers. The House of Representatives, whose members represent the people, has the power to propose all the bills. Senate has the power to approve the treaties and some appointments made by the President.
