Just so you know, Here are the three branches of American Government:
The executive, legislative, and judicial
From the WIKI: Federal government of the USA
The federal government has three branches: the executive, legislative, and judicial. Through a system of separation of powers, each of these branches has some authority to act on its own, some authority to regulate the other two branches, and has some of its authority, in turn, regulated by one or both of the other branches.
