1. #39 The 25 th Amendment to the United States Constitution The amendment was proposed in Congress on January 6, 1965 (Senate version, drafted by Sen. Birch Bayh) and July 6, 1965 (House version, proposed by Rep. Emanuel Celler). Hearings were held through February 19, in which the Senate passed the amendment (then known as "Senate Joint Resolution 1") by a unanimous 72-0 vote. The House passed a modified form of the amendment on April 13 by a 368-29 margin, and after a conference committee ironed out differences between the versions, on July 6, 1965 the final version of the amendment was passed by the Senate and presented to the states for ratification. Just six days after its submission, Wisconsin (by an 84-11 margin in the State Assembly and 28-0 in the Wisconsin Senate) and Nebraska were the first states to ratify the amendment. On February 10, 1967, Minnesota and Nevada were the 37th and 38th states to ratify, and in a ceremony in the East Room of the White House, General Services Administrator Lawson Knott certified that the amendment was part of the United States Constitution on February 23, 1967.

19. Order of Presidential Succession According to the Presidential Succession Act of 1792, the Senate president pro tempore1 was next in line after the vice president to succeed to the presidency, followed by the Speaker of the House. In 1886, however, Congress changed the order of presidential succession, replacing the president pro tempore and the Speaker with the cabinet officers. Proponents of this change argued that the congressional leaders lacked executive experience, and none had served as president, while six former secretaries of state had later been elected to that office. The Presidential Succession Act of 1947, signed by President Harry Truman, changed the order again to what it is today. The cabinet members are ordered in the line of succession according to the date their offices were established. Prior to the ratification of the 25th Amendment in 1967, there was no provision for filling a vacancy in the vice presidency. When a president died in office, the vice president succeeded him, and the vice presidency then remained vacant. The first vice president to take office under the new procedure was Gerald Ford, who was nominated by Nixon on Oct. 12, 1973, and confirmed by Congress the following Dec. 6.25th Amendment
