Nelson Rockefeller is sworn in as Vice President of the United States under President Gerald Ford under the provisions of the Twenty-fifth Amendment to the United States Constitution.

Nelson Aldrich "Rocky" Rockefeller was the 41st vice president of the United States, serving from 1974 to 1977 under President Gerald Ford. A member of the Republican Party and the wealthy Rockefeller family, he was the 49th governor of New York from 1959 to 1973. He was the leader of the moderate faction of his party, known as the Rockefeller Republicans.

The vice president of the United States is the second-highest ranking office in the executive branch of the U.S. federal government, after the president of the United States, and ranks first in the presidential line of succession. The vice president is also an officer in the legislative branch, as the president of the Senate. In this capacity, the vice president is empowered to preside over the United States Senate, but may not vote except to cast a tie-breaking vote. The vice president is indirectly elected at the same time as the president to a four-year term of office by the people of the United States through the Electoral College, but the electoral votes are cast separately for these two offices. Following the passage in 1967 of the Twenty-fifth Amendment to the US Constitution, a vacancy in the office of vice president may be filled by presidential nomination and confirmation by a majority vote in both houses of Congress.

Gerald Rudolph Ford Jr. was the 38th president of the United States, serving from 1974 to 1977. A member of the Republican Party, Ford assumed the presidency after the resignation of President Richard Nixon, under whom he had served as the 40th vice president from 1973 to 1974 following Spiro Agnew's resignation. Prior to that, he served as a member of the U.S. House of Representatives from 1949 to 1973.

The Twenty-fifth Amendment to the United States Constitution addresses issues related to presidential succession and disability.
