Reasonable chance he never wrote one and Biden just said that to pacify the media.

Here is the full text of the letter that Obama left 45. I'd never thought to read it.

Dear Mr. President -

Congratulations on a remarkable run. Millions have placed their hopes in you, and allof us, regardless of party, should hope for expanded prosperity and security during your tenure.

This is a unique office, without a clear blueprint for success, so I don’t know that any advice from me will be particularly helpful. Still, let me offer a few reflections from the past 8 years.

First, we’ve both been blessed, in different ways, with great good fortune. Not everyone is so lucky. It’s up to us to do everything we can (to) build more ladders of success for every child and family that’s willing to work hard.

Second, American leadership in this world really is indispensable. It’s up to us, through action and example, to sustain the international order that’s expanded steadily since the end of the Cold War, and upon which our own wealth and safety depend.

Third, 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.

And finally, take time, in the rush of events and responsibilities, for friends and family. They’ll get you through the inevitable rough patches.

Michelle and I wish you and Melania the very best as you embark on this great adventure, and know that we stand ready to help in any ways which we can.

Good luck and Godspeed,

BO

A few notes:

Obama forecast 45s disregard for "rule of law, separation of powers, equal protection and civil liberties". He KNEW 45 would fuck that up.

The role all Presidents, since Reagan, have played in "sustain[ing] the international order that’s expanded steadily since the end of the Cold War, and upon which our own wealth and safety depend" is a warning about fomenting or courting instability. It is also a tacit admission of the Military-Industrial complex and its attendant supports in entertainment, energy, and finance that projects American values and superiority worldwide. He KNEW 45 would fuck that up, too.

Finally, and from the start of the letter, "we’ve both been blessed... Not everyone is so lucky" is a reminder that the office is meant to support the less fortunate. We all KNEW 45 would fuck that up.

Bold of you to assume Trump knows how to write and the letter was at all legible.

Trump is planning to release it in two weeks. Just two more weeks.

He still claims he won. If he won, why would he write a letter?

Narcissistic prick.

I would be shocked to learn that he “wrote” one. (Less shocked to learn Stephen Miller wrote one for him)

He has concepts of a letter and as soon as he gets a letter that is better than the one that Barack Obama wrote then he'll announce it.

They say Biden is still waiting to talk to Trump to this very day.

Found it!

Joe,

Well, Joe, you made it. A lot of people said you wouldn’t. Frankly, I’m surprised, but here we are. You know, this job—it’s not easy. People don’t understand. They think they know, but they have no idea. Believe me, it’s the toughest job in the world. I did it better than anyone ever has, that I can tell you. People say it all the time. But now it's your turn. Let’s see what you’ve got.

You’re going to learn quickly, Joe. The media? They’ll love you at first. They’re on your side now, we all know that, OK? They never treated me fairly. It was a witch hunt from day one. Fake news—nonstop. But here’s the thing: they’ll turn on you too. Trust me, they always do. And when they do, you’ve got to be ready. They’re not your friends, Joe. They never were.

Let’s talk about the swamp. You know it’s bad, I know it’s bad—everybody knows it’s bad. But it’s worse than you think. Much worse. They’ll smile to your face and stab you in the back. I cleaned a lot of it up—did an incredible job, by the way—but you’ve got to watch out. You’ve been here 47 years, but I don’t think you’ve seen what I’ve seen. Be strong, Joe. You’re going to need to be stronger than you’ve ever been.

America First, Joe. Always. I rebuilt this country. Best economy in history. Nobody’s ever seen anything like it. Record jobs, record stock market, and then—boom—the China virus hit. Total disaster. But we handled it amazingly. You’re inheriting something great, don’t mess it up. People love America First, Joe. You’d better not forget that. The radical left—they’ll try to pull you away from it. Don’t let them do it. They’ll ruin everything. Believe me, they’re bad news. Very bad news.

And here’s the thing: they’ll tell you to undo everything we did—big mistake. Huge. The military? I rebuilt it. Our trade deals? Best deals we’ve ever had. You don’t want to go back to the old way. It was a disaster before me. Total disaster. Keep what works, Joe, even if they tell you not to. They won’t admit it, but they know I was right. Everybody knows it.

Anyway, Joe, good luck. You’re gonna need it. We’ll see what happens, right? A lot of people are watching. And you never know, maybe I’ll be back in 2024. People are talking about it. A lot of people.

Donald J. Trump
45th President of the United States

P.S. Don’t let Kamala take over. I hear she’s already measuring the drapes. Sad!

Edit: forgot to mention that this is not the real letter. Obviously.

I'm not sure how to help with FOIA, but my sleuthing align with your findings, this letter never went public.

Huh I thought these weren't released, but googling shows they are.

Try starting here

I suppose I'll try submitting one too

The only thing that was ever said was that it was "generous"

Wtf does that mean?

It's probably either in a yet-to-be-discovered bankers box at Mar-A-Lago, or sitting in an evidence locker after having been found in one.
