4. A Vice-President is elected at the same time and in the same way, who, in case of the President’s death, removal, resignation, or inability to discharge the duties of his office, becomes acting President during the remainder of his term, or while the disability continues. The first Congress passed a law giving the President a salary of $25,000 per annum, with the use of a furnished house, and it remained the same until 1873, when it was raised to $50,000 per year. He is forbidden by the Constitution to receive any other public income during his term of office, nor is he at liberty to accept presents from any foreign power. Before entering on the duties of his office he is required to take an oath “to preserve, protect, and defend the Constitution of the United States,” to the best of his ability. 5. It is required that he shall be a native-born citizen of the United States, that he shall have been fourteen years a resident in the United States, and that he shall not be less than thirty-five years of age; which are designed to insure his attachment to American interests, his thorough acquaintance with American affairs, and the full maturity of his mind and character. 6. It is his duty to appoint such officers in every department of the public service as are not otherwise provided for. He usually sends the nomination to the Senate for their approval or consent, and when that is given appoints them by commission, signed with his name, to the office. In this manner he nominates the Justices of the Supreme Court, ambassadors, resident ministers, chargé-d’affaires, consuls, and other representatives of the government abroad, all the Heads of Executive Departments, and the more important subordinate officers of each department. When the Senate is not in session he may appoint all these directly, to serve until it meets again. The clerks and minor officers are usually appointed by Heads of Departments. In all other cases the advice and consent of the Senate are required before the appointment and commission can be legal. 7. It is his duty to make treaties with Foreign Powers, but these require confirmation by two-thirds of the Senate to be valid. He receives the Representatives of Foreign Powers, and superintends all diplomatic intercourse with them and with our own Representatives abroad. He is commander-in-chief of the army and navy, and must sign the commissions of all the officers in each. He may grant reprieves and pardons at his discretion, except in cases of impeachment, and he is required to approve and sign the laws passed by Congress before they can take effect. If he does not approve a law he “vetoes” it by returning it to Congress, with his reasons for not signing it. If that body reconsiders it and reënacts it by a two-thirds vote of each house, it may become a law without his signature.
