Step-by-step explanation:
The issue of a disagreement regarding the disability of the president and the transfer of duties to the Vice President is resolved by the 25th Amendment to the Constitution. This amendment outlines a plan for the continuation of government and provides procedures for the vice president to assume power in cases of presidential disability.
