It's customary for departing US Presidents to write a letter to the leader about to take over the White House.
They usually including best wishes, advice for the future and poignant ideas about what it means to be President of the United States of America.
When leaving the Oval Office, Barack Obama wrote to Trump: "We are just temporary occupants of this office. That makes us guardians of those democratic institutions and traditions - like rule of law, separation of powers, equal protection and civil liberties - that our forebears fought and bled for.

"Regardless of the push and pull of daily politics, it's up to us to leave those instruments of our democracy at least as strong as we found them."
Despite Trump not being present at Joe Biden's inauguration, breaking with a longstanding tradition, the 45th President has reportedly followed suit with the letter.
The only problem is, we have no idea what he's written. However, people on social media have been ruthlessly speculating what it might be.
Sharing a photo of a spoof note, comedian Sooz Kempner tweeted: "Whoa this is the letter Trump left for Biden!!!"

Referencing one of the best episodes of Come Dine With Me to have graced our screens, the handwritten note read: "Dear Joe. You won Joe. Enjoy the power. I hope it makes you happy.
"Dear Lord what a sad little life, Joe. You ruined my election completely so you could have the power and I hope you can use it and get some lessons in grace and decorum. Because you have all the grace of a reversing dump truck without any tyres on. Have a good life! DONALD."
Others took inspiration from Sex and the City, and Berger's post-it break-up that left Carrie absolutely raging in series six.
Someone else's efforts involved a childlike message scribbled in pencil, which said: "I'm angry at you and I'm not talking to you today and tomorrow."

Another, addressed to 'Sleepy Joe', read: "Your a mean cheat, I won bigly. Covfefe, Donald Trump."
Having left his letter for Biden, Trump exited the White House and flew to Florida.

Speaking to a small crowd during his official farewell speech, Donald Trump said: "We have the greatest country in the world, we have the greatest economy in the world, and as bad as the pandemic was [...] we did something that is really considered a medical miracle.
"I just want to say you are amazing people. This is a great, great country. It is my greatest honour and privilege to have been your president.
"I will always fight for you. I will be watching. I will be listening and I will tell you that the future of this country has never been better.
"Have a good life, we will see you soon."
