Public money is but a species of public property. It can not be raised by taxation or customs, nor brought into the Treasury in any other way except by law; but whenever or howsoever obtained, its custody always has been and always must be, unless the Constitution be changed, intrusted to the executive department. No officer can be created by Congress for the purpose of taking charge of it whose appointment would not by the Constitution at once devolve on the President and who would not be responsible to him for the faithful performance of his duties. The legislative power may undoubtedly bind him and the President by any laws they may think proper to enact; they may prescribe in what place particular portions of the public property shall be kept and for what reason it shall be removed, as they may direct that supplies for the Army or Navy shall be kept in particular stores, and it will be the duty of the President to see that the law is faithfully executed; yet will the custody remain in the executive department of the Government. Were the Congress to assume, with or without a legislative act, the power of appointing officers, independently of the President, to take the charge and custody of the public property contained in the military and naval arsenals, magazines, and storehouses, it is believed that such an act would be regarded by all as a palpable usurpation of executive power, subversive of the form as well as the fundamental principles of our Government. But where is the difference in principle whether the public property be in the form of arms, munitions of war, and supplies or in gold and silver or bank notes? None can be perceived; none is believed to exist. Congress can not, therefore, take out of the hands of the executive department the custody of the public property or money without an assumption of executive power and a subversion of the first principles of the Constitution.
