If by the assertion of this claim of right to call upon the Executive for all the information in its possession relating to any subject of the deliberation of the House, and within the sphere of its legitimate powers, it is intended to assert also that the Executive is bound to comply with such call without the authority to exercise any discretion on its part in reference to the nature of the information required or to the interests of the country or of individuals to be affected by such compliance, then do I feel bound, in the discharge of the high duty imposed upon me "to preserve, protect, and defend the Constitution of the United States," to declare in the most respectful manner my entire dissent from such a proposition. The instrument from which the several departments of the Government derive their authority makes each independent of the other in the discharge of their respective functions. The injunction of the Constitution that the President "shall take care that the laws be faithfully executed" necessarily confers an authority commensurate with the obligation imposed to inquire into the manner in which all public agents perform the duties assigned to them by law. To be effective these inquiries must often be confidential. They may result in the collection of truth or of falsehood, or they may be incomplete and may require further prosecution. To maintain that the President can exercise no discretion as to the time in which the matters thus collected shall be promulgated or in respect to the character of the information obtained would deprive him at once of the means of performing one of the most salutary duties of his office. An inquiry might be arrested at its first stage and the officers whose conduct demanded investigation may be enabled to elude or defeat it. To require from the Executive the transfer of this discretion to a coordinate branch of the Government is equivalent to the denial of its possession by him and would render him dependent upon that branch in the performance of a duty purely executive.
