For the first time in six months, The Donald got in front of a press pool to take questions from reporters.
The televised conference in New York was dominated by allegations of shady dealings with Russia, following salacious and unverified documents published by Buzzfeed News.
During the hour-long event, the incoming 45th US president called BuzzFeed News a "failing pile of garbage" and refused to take a question from a CNN reporter, saying: "Your organisation's terrible... You are fake news".
Here are five things we learned.
1. We're not going to see his tax returns
When questioned about this, he replied:"I won. I don't think they (the American people) care at all."
He also said journalists seemed to be the only species of people interested in seeing them.
2. He's going to hand over the Trump business empire to his sons
Sons Donald Jr and Eric will now apparently take control of the vast Trump brand. He even brought along a tower of papers to prove it.
Trump also claimed he rejected a $2 billion deal in Dubai last weekend to prove he was putting America First.
Daughter Ivanka will apparently be removed from her positions in the company as her husband is a senior aide.
Plus, he promised to donate profits from foreign government payments to his hotels to the US treasury.
And, if his sons do a bad job at the end of his tenure as president they'll be met with his "you're fired" slogan, he said, signing off with the cheesy line.
3. His relations with intelligence agencies are at rock-bottom
Trump pointed the finger at US spooks, suggesting they may have released the eyebrow-raising documents about him.
He said it would be a "tremendous blot" on their reputations if it was proved they had leaked it.
The dossier alleges Russia had compromising information on Trump and that the Kremlin and his campaign team were in contact.
It also detailed alleged detailed prostitution use and acts of sexual depravity, which Trump furiously denied.
4. Somehow, Mexico WILL pay for the wall
Despite reports he was rolling back on the famous campaign pledge, he was adamant "Mexico will reimburse us... through a payment or a tax. Probably not a payment."
So a tax, then?
Former Mexican president Vicente Fox Quesada tweeted about the affair.
5. Trump hates uncleanliness
Some of the more, ahem, vivid claims in the "leaked" dossier couldn't possibly be true, Trump said, as he was "germaphobe".
The high-profile billionaire also said he had long been acutely aware of the existence of tiny hidden cameras in hotel rooms.
"In your hotel rooms, you're probably going to have cameras... in the strangest places... you better be careful or you'll be watching yourself on nightly televison," he said.
