Twenty-second Amendment to the United States Constitution
The Twenty-second Amendment (Amendment XXII) to the United States Constitution sets a limit on the number of times an individual is eligible for election to the office of President of the United States, and also sets additional eligibility conditions for presidents who succeed to the unexpired terms of their predecessors.
First 100 days of Barack Obama's presidency
According to the Twentieth Amendment to the United States Constitution, Section 1: "The terms of the President and Vice President shall end at noon on the 20th day of January". Thus, Bush had relinquished the Presidency at 12:00. According to the Twentieth Amendment to the United States Constitution, Section 3: If, at the time fixed for the beginning of the term of the President... if the President elect shall have failed to qualify, then the Vice President elect shall act as President until a President shall have qualified." By Article Two, Section 1, Clause 8 of the Constitution and Amendment 20, Some feel that Obama was not able to assume the Presidency until 12:05. In fact, since Obama did not complete his oath until 12:01, there was further speculation as to who was President for the first minute after Bush relinquished control.
