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

When the President is unable to continue in their role due to death, resignation, removal from office, or incapacitation, the Vice President automatically assumes the presidency. This process is established by the Presidential Succession Act and the 25th Amendment to the Constitution.

The role of the Vice President is specifically designed to be the immediate successor to the President. This ensures a continuity of leadership and stability in the executive branch of government. The Vice President is trained and prepared for this responsibility, making the transition smoother and maintaining the integrity of the office.

The other options, while they hold significant positions in government, do not follow the line of succession established by law. The Chief Justice presides over the Supreme Court, the Speaker of the House manages the legislative body (but only ascends to the presidency after the Vice President), and the Secretary of State oversees foreign affairs, but is not in the line of presidential succession. Hence, the Vice President is the correct answer as the immediate successor to the presidency.
