If the President can no longer serve, who becomes President?

The Vice President is the individual who assumes the presidency if the President is unable to continue in their role. This process is established by the Presidential Succession Act and the 25th Amendment to the Constitution. The Vice President serves directly under the President and is next in line to the presidency, ensuring a continuity of leadership in the executive branch.

This is a crucial safeguard in the U.S. government, as it provides a clear and immediate successor to the presidency, thereby maintaining stability and the effective functioning of government. Other leaders, such as the Secretary of State, the Speaker of the House, or the Chief Justice, do not have the constitutional authority to step into the presidency in the absence of the sitting President.
