What is the 25th Amendment?

The 25th Amendment provides the constitutional framework for presidential succession and the transfer of power when a president is unable to discharge their duties. While the first three sections address the line of succession, vice-presidential vacancies, and voluntary transfers of power—frequently utilized for medical procedures—Section 4 remains the most contentious. This provision allows the Vice President and a majority of the cabinet to declare a president incapacitated, though it has never been invoked. Historically, the amendment emerged from the need for clarity following the death of John F. Kennedy and the realization that informal, behind-the-scenes arrangements were insufficient during the Cold War. Constitutional experts Lana Ulrich and Linda Monk emphasize that the amendment relies heavily on the political judgment of executive branch officials, highlighting the ongoing tension between constitutional text and practical application during periods of national crisis.
