The inauguration marks the official transfer of presidential power, with the executive branch changing hands from the Biden administration to the Trump administration. The 20th Amendment states that a president's four-year term ends at noon on Jan. 20, and the president-elect is sworn in shortly after.

Donald Trump will be sworn in as president of the United States on Monday, ushering in his second term in office and capping one of the most astounding political comebacks in American history.
