Answer: The United States Government is divided into three branches legislative, executive, and judicial. Each branch has its own powers and is kept from getting too much power by the system of "checks and balances".
Explanation:
The legislative branch is responsible for making new laws. The executive branch (which includes the President) can veto the proposed laws and the judicial branch (which includes the Supreme Court) can declare the law unconstitutional.
The executive branch is responsible for enforcing Federal laws. As said before the President in the executive branch can veto a law but the legislative branch through the Supreme Court can override that veto if enough Justices agree.
The legislative branch approves or declines Presidential nominations for executive positions. The branch also controls the entire budget of the United States. The judicial branch can deny new nominations if enough Justices agree.
The judicial branch which includes the Supreme Court consists of judges nominated by the President in the executive branch but the legislative branch can confirm or deny those nominations.
