Final answer:
The 25th Amendment to the U.S. Constitution provides for the vice president to assume the presidency in the event of the president's death, incapacity, or resignation. It establishes the process for presidential succession and dealing with presidential disability, including specifying the role of the vice president and cabinet in these situations.
Step-by-step explanation:
The amendment that provides for the vice president to assume the presidency in the event of the chief executive's death or incapacity, and sets forth the procedures to be followed, is the 25th Amendment. This amendment was adopted in 1967, and it clarifies the line of succession as well as the process for dealing with presidential disability. It consists of several key sections: Section 1 states that upon the president's removal, death, or resignation, the vice president shall become president. Section 2 allows the president to nominate a new vice president when there is a vacancy, which requires confirmation by a majority vote of both Houses of Congress. Section 3 outlines how the president can declare themselves unable to perform their duties, with the vice president then serving as acting president. Lastly, Section 4 details the process by which the vice president and a majority of the cabinet can declare the president unable to discharge their duties, making the vice president acting president.
The Presidential Succession Act of 1947 established the line of succession beyond the vice president, but the 25th Amendment further elaborated on this topic by addressing presidential disability and succession, as well as filling a vice presidency vacancy.
