President Biden wrote President-elect Donald Trump a letter as he departed the White House, keeping to tradition. As Biden awaited Trump’s arrival at the White House, he was asked if he wrote a letter to Trump.

"Maybe we should all read it together," Trump told reporters upon finding Biden's letter. "Maybe I'll read it first and then make that determination."

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.
