Scenario pages explain formal political processes and plausible dynamics, not predictions.
Briefing Sections
Section 1
Voluntary transfer under Section 3
The president can voluntarily transfer power to the vice president by sending written notice to Congress. This has been used routinely during medical procedures — the vice president serves as acting president until the president sends a second letter reclaiming power.
Section 2
Involuntary transfer under Section 4
If the president cannot or will not declare their own inability, the vice president and a majority of the principal officers of the executive departments can send a written declaration to Congress that the president is unable to discharge the powers and duties of the office. The vice president immediately becomes acting president.
Section 3
The president can challenge the declaration
The president can transmit a declaration that no inability exists, reclaiming power. If the vice president and cabinet disagree, they have four days to re-submit their declaration, and Congress must decide the issue.
Section 4
Congress makes the final determination
If Congress must decide, it has 21 days to vote. A two-thirds majority of both houses is required to keep the vice president as acting president. Otherwise, the president resumes power. This process has never been used and would represent an extreme constitutional crisis.
