Monday’s change of Oval Office occupants is a ritual full of traditions and customs. One of the more modern ones began in 1989, when Ronald Reagan left a note for George H.W. Bush on stationery with a whimsical bit of advice.

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

A look at the history of presidential letters and whether President Biden will continue the tradition by writing a note for his predecessor-turned-successor, Donald Trump.

WASHINGTON — Ronald Reagan probably didn't realize he was ... desk drawer after two terms as president. He did that for George H.W. Bush, his successor and vice president of eight years.

Ever since the second and third presidents, John Adams and Thomas Jefferson, died on the same day — July 4th, 1826, the 50th anniversary of the Declaration of Independence — the American presidency has thrown up a goodly number of calendrical coincidences.

Nowadays, every American President carries on a unique tradition of leaving a letter in the Resolute Desk of the Oval Office.

The American people - and people around the world - look to this house for steadiness in the inevitable storms of history,’ Biden tells Trump

Former President Jimmy Carter’s recent death and funeral reminded Americans of his legacy and the values that motivated his public service.

In his first hours as president, Trump signed numerous executive orders to implement his administration's promises.

President Donald Trump redecorated the Oval Office with many of the same artifacts from his first White House term.

President Trump found a handwritten letter from outgoing President Biden in the Oval Office’s Resolute Desk, continuing a longstanding tradition of presidential transitions.
