The secret contents of former President Joe Biden's letter to Donald Trump were revealed by Peter Doocy, a Fox News correspondent, on X on Wednesday.

President Joe Biden has adhered to the tradition started by Ronald Reagan and left his successor, Donald Trump, a letter as he hands over power.Biden confirmed that he wrote Trump a letter, but he didn’t say what he wrote to the 47th president,

The tradition of the outgoing president leaving the incoming president a letter started with Ronald Reagan in 1989. Reagan left a note for his successor George H.W. Bush, who served as his vice president for eight years. President Trump left a note for Biden when Biden took office in 2021, but the contents of the letter have never been shared.

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.

Ronald Reagan started a tradition as he prepared to leave office after two terms as president: Write a note congratulating your successor and leave it in the Oval Office desk drawer.

A year ago, a survey of presidential scholars put him in the top third of chief executives while Trump ranked last. But that was before the 2024 election and campaign.

The rug, which was in place during Ronald Reagan’s administration and during Trump’s first term, was reinstalled during Trump’s inauguration ceremony, according to CBS News. The Resolute Desk had to be partially disassembled in order to facilitate its return.

Donald Trump shared details about a 'nice' and inspirational letter former President Joe Biden left for him at the White House Resolute Desk. The letter continues an inauguration tradition initiated by Ronald Reagan.

"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."
