Every president since Ronald Reagan has left a note for his successor, and President Biden could be the first to write a letter to someone who is both his successor and the predecessor who left a note for him.

Before he leaves office for the final time, President Joe Biden plans to pen President-elect Donald Trump a letter, CNN is told.

The president will deliver his final remarks from the Oval Office. In the past, President Barack Obama went to his home in Chicago for his farewell speech. George W. Bush spoke from the East Room. Bill Clinton spoke from the Oval Office. Donald Trump delivered a pre-taped address that was made public Jan. 19, 2021.
