Biden expected to leave Trump letter, continuing tradition since Reagan

Fox News Digital reached out to the White House for confirmation but did not immediately hear back.

Four years after succeeding Trump, Biden finds himself in the unique position, in both history and politics, of writing a letter to his successor who left a note for him four years ago.

Biden said it was a "very generous letter," but has so far declined to share the content of what Trump wrote, deeming it private and saying he wouldn't discuss it until he had a chance to speak with Trump. 

Trump has also declined to share details, saying he thought it was up to Biden to share the letter.

"It was a nice note," Trump said during a September 2023 interview with NBC's "Meet the Press," adding, "I took a lot of time in thinking about it."

When Trump takes office on Monday, he'll be the first president to serve nonconsecutive terms since Grover Cleveland in the late 1800s, when the letter-writing tradition didn't exist.
