It is alike due to the subject, the Senate, and the people that the views which I have taken of the proceedings referred to, and which compel me to regard them in the light that has been mentioned, should be exhibited at length, and with the freedom and firmness which are required by an occasion so unprecedented and peculiar.
Under the Constitution of the United States the powers and functions of the various departments of the Federal Government and their responsibilities for violation or neglect of duty are clearly defined or result by necessary inference. The legislative power is, subject to the qualified negative of the President, vested in the Congress of the United States, composed of the Senate and House of Representatives; the executive power is vested exclusively in the President, except that in the conclusion of treaties and in certain appointments to office he is to act with the advice and consent of the Senate; the judicial power is vested exclusively in the Supreme and other courts of the United States, except in cases of impeachment, for which purpose the accusatory power is vested in the House of Representatives and that of hearing and determining in the Senate. But although for the special purposes which have been mentioned there is an occasional intermixture of the powers of the different departments, yet with these exceptions each of the three great departments is independent of the others in its sphere of action, and when it deviates from that sphere is not responsible to the others further than it is expressly made so in the Constitution. In every other respect each of them is the coequal of the other two, and all are the servants of the American people, without power or right to control or censure each other in the service of their common superior, save only in the manner and to the degree which that superior has prescribed.
The responsibilities of the President are numerous and weighty. He is liable to impeachment for high crimes and misdemeanors, and on due conviction to removal from office and perpetual disqualification; and notwithstanding such conviction, he may also be indicted and punished according to law. He is also liable to the private action of any party who may have been injured by his illegal mandates or instructions in the same manner and to the same extent as the humblest functionary. In addition to the responsibilities which may thus be enforced by impeachment, criminal prosecution, or suit at law, he is also accountable at the bar of public opinion for every act of his Administration. Subject only to the restraints of truth and justice, the free people of the United States have the undoubted right, as individuals or collectively, orally or in writing, at such times and in such language and form as they may think proper, to discuss his official conduct and to express and promulgate their opinions concerning it. Indirectly also his conduct may come under review in either branch of the Legislature, or in the Senate when acting in its executive capacity, and so far as the executive or legislative proceedings of these bodies may require it, it may be exercised by them. These are believed to be the proper and only modes in which the President of the United States is to be held accountable for his official conduct.
