I think it absolutely necessary that the President should have the power of removing his subordinates from office; it will make him, in a peculiar manner, responsible for their conduct, and subject him to impeachment himself, if he suffers them to perpetrate with impunity high crimes or misdemeanors against the United States, or neglects to superintend their conduct, so as to check their excesses.
James MadisonThe important distinction so well understood in America between a constitution established by the people, and unalterable by the government; and a law established by the government, and alterable by the government, seems to have been little understood and less observed in any other country. Wherever the supreme power of legislation has resided, has been supposed to reside also, a full power to change the form of government.
