Former President Joe Biden has continued a tradition started by President Ronald Reagan, who left behind a letter in the White House for his successor, George H.W. Bush.

President Joe Biden will leave a letter for President-elect Donald Trump before leaving the Oval Office for the final time on Monday as part of tradition among outgoing presidents, according to a report.

Every president since Ronald Reagan has left a note for his successor, and President Joe 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.
