When most people think of the Executive Department, they think of the President. One of the primary responsibilities of the President is to enforce the laws of the land. However, over the past two hundred years, the size of our country has demanded a complex infrastructure to assist the president in this overwhelming job. Subsequently, millions of federal employees work under the fourteen executive agencies. Each of these departments is led by a Secretary. For example, the Department of Commerce (DOC) is led by William M. Daley, the Secretary of Commerce. Each of these departments is then broken into smaller agencies which deal with issues ranging from immigration to the mining of silver, from the Coast Guard to the making of money, and from life threatening diseases to fish and wildlife.
