The United States Government is constitutionally divided into three branches: the legislative, the judicial, and the executive. The legislative branch comprises the Congress, in 1943 elected by popular suffrage. The judicial power is vested in the Supreme Court. The executive power is vested in the President and the Executive of US government includes 10 departments. Both the departments of State and Treasury are among these.
 
 

'Article II, section 1, of the Constitution provides that "the executive Power shall be vested in a President of the United States of America. He shall hold his Office during the Term of four years,...together with the Vice President, chosen for the same term...". In addition to the powers set forth in the Constitution, the statutes have conferred upon the President specific authority and responsibility covering a wide range of matters ( United States Code Index ).

'The President is the administrative head of the Executive Branch of the Government, which includes numerous agencies, both temporary permanent, as well as the 10 executive departments. The heads of the 10 executive departments form the Cabinet and serve in an advisory capacity to the President. They are the Secretary of State, the Secretary of  the Treasury, the Secretary of War, the Attorney General, the Postmaster General, the Secretary of the Navy, the Secretary of the Interior, the Secretary of Agriculture, the Secretary of Commerce, and the Secretary of Labor. Upon invitation of the President, other Federal executives may attend Cabinet meetings.'
