U.S. Government/U.S. Laws

U.S. Government
The federal government of the United States is the national government of the constitutional republic of the fifty states that is the United States of America.  The federal government includes three distinct branches of government: legislative, executive, and judiciary.  These branches have various powers defined by the U.S. Constitution.

Executive Branch 
The executive branch of the government is responsible for enforcing the laws of the land. The president, vice president, department heads (cabinet members), and heads of independent agencies carry out this mission.
Judicial Branch
Courts decide arguments about the meaning of laws and how they are applied. They also decide if laws violate the Constitution—this is known as judicial review, and it is how federal courts provide checks and balances on the legislative and executive branches.
Legislative Branch
Article I of the Constitution establishes the legislative or law making branch of government. It has a two-branch Congress—the Senate and the House of Representatives—and agencies that support Congress.
