If the President can no longer serve, who takes over as President?

When the President can no longer serve due to resignation, removal, death, or incapacitation, the Vice President assumes the office of the President. This process is established by the Presidential Succession Act and is outlined in the 25th Amendment to the U.S. Constitution. The Vice President is the next in line and has been elected to that position, ensuring a continuity of leadership and stability in government.

In contrast, the other positions listed do not have the authority to take over as President. The Secretary of State, while an important member of the Cabinet responsible for foreign affairs, is not in the presidential line of succession. The Senate President, typically the Vice President, serves primarily a legislative role and does not take over as President unless the Vice President slot is vacant. Lastly, the Chief of Staff is a senior aide to the President, managing the executive office but is not part of the official line of succession. Therefore, the Vice President is the correct answer, as this ensures a clear and constitutional process for leadership transition.
