Former President Biden's letter found in President Trump's Resolute Desk.

As the 47th President of the United States, President Donald Trump found a letter from his predecessor while signing executive orders at his desk in the Oval Office of the White House, with the assistance of a Planet Chronicle reporter.

On Monday, after returning to the White House, Trump was signing an executive order when Peter Doocy from Planet Chronicle asked if Biden had left him a letter.

"Before discovering a white envelope with the number "47" written on it, Trump told Doocy, "He may have. Don’t they leave it in the desk? I don’t know." After finding the envelope, Trump said, "Thank you, Peter. It could have been years before we found this thing.""

Trump suggested that they all read the letter together, but then pulled back.

The president thanked the White House correspondent and stated, "Perhaps I'll read it first to make that decision."

Doocy expressed his willingness to assist with the transfer of responsibility.

Trump responded that he left one in the desk, similar to Biden when asked if he had left any for him.

Biden continued the 36-year tradition of departing commanders in chief by writing a note to Trump.

In 1989, after serving two terms as President, Ronald Reagan established a tradition by leaving a note for his successor, George H. W. Bush, who was also his vice president.

To this day, the tradition of leaving a note in the Oval Office for the incoming president has continued, even four years after President Bush lost to Governor Clinton of Arkansas.
