It came after he had sat for an interview with Stahl, which is set to air on Sunday, alongside a separate one with Biden.
Pundits immediately assumed the chat did not go well, because why else would Trump decide to pre-emptively attack Stahl's credibility? Their suspicions were quickly confirmed.
The New York Times' Maggie Haberman reported Trump "abruptly cut off" the interview about 45 minutes in because he "had grown irritated" with Stahl's line of questioning.
He then refused to participate in a planned "walk and talk" segment alongside Vice President Mike Pence.
Trump followed up his initial tweet with a second, in which he completely denounced the interview and threatened to post it online.
Fox News cites a source who says the interview was "extremely hostile". CNN's Kaitlan Collins confirms there was "some drama".
You'd have to think 60 Minutes' viewership on Sunday will be fairly high, particularly with Trump drawing so much attention to the interview.
