Which Vice President was sworn in on Air Force One as the 36th President of the United States?

• A. Richard Nixon
• B. Spiro Agnew
• C. Hubert Humphrey
• D. Lyndon Baines Johnson

Answer: (D)

Lyndon Baines Johnson was the Vice President who, upon Kennedy’s assassination, automatically became the 36th President and was sworn in right away aboard Air Force One. The oath was administered by U.S. District Judge Sarah T. Hughes on the tarmac at Dallas Love Field, underscoring how the vice presidency ensures immediate continuity of government.

This moment shows how the presidential line of succession works in practice: when the sitting president can no longer serve, the Vice President steps in and takes the oath to assume the duties of the office. The setting aboard Air Force One reflects the urgency and immediacy of the transfer, with the aircraft’s call sign already tied to the presidency as soon as the president is aboard.

Among the other names, they are all notable figures in U.S. politics, but none fits the description of being sworn in as president on Air Force One to become the 36th President.
