What is the 25th amendment to US Constitution?

The 25th amendment to the Constitution of USA  passed by Congress on July 6, 1965 brought  a procedure within constitution to  provide a process for the president to withdraw from office, voluntarily and temporarily.

The process involves Congress to notify  that the President is unable to discharge his powers and duties. After that ,the vice president takes over as acting president until the president notifies Congress that he is fit to return.In the case of a death of a president, the vice president becomes president. In that event, the new president would name a vice president who would be subject to confirmation by a majority vote in both chambers of Congress.

Section 4 of the 25th Amendment provides that a president who “is unable to discharge the powers and duties of his office” can be removed from office. The vice president and either a majority of Cabinet members or members “of such other body as Congress may by law provide” need to communicate that wish in writing to the Senate president pro tempore and the Speaker of the House in order for the sitting vice president to become the acting president. However, if the president resists and deems himself capable of fulfilling his duties, the matter heads to Congress: A two-thirds vote in both the House and Senate within 21 days means the vice president remains the acting president; a lesser vote returns the powers to the president.
