United States Government
The United States Government is the federal government of the United States of America. Under the United States Constitution, government in the United States is organized according to a system of dual sovereignty. That is, the Constitution enumerates certain powers to the federal government, while the states retain the rest. That principle is inherent in Article I and explicitly stated in the Tenth Amendment.
The Constitution also provides for separation of powers. The legislative power is vested in Congress; the executive power, in the President of the United States of America and in various inferior executive bodies; and the judicial power, in the United States Supreme Court and in various inferior federal courts.
