In the United States, the executive branch is one of the three branches or divisions of the government. The executive branch is headed by the president, who is the head of state for the United States and the leader of the executive branch. Other members of the executive branch include persons, offices, and departments that are responsible for carrying out and enforcing the laws of the land.
The executive branch was created as part of the separation of powers arrangement developed by the authors of the United States Constitution. They divided the responsibilities and the powers of the government as a whole into the legislative branch, which is responsible for establishing the law; the executive branch, which administers the law; and the judicial branch, which interprets laws and insures that they are in agreement with the Constitution.
In America the head of state is the president.
