The author of Moneyball and The Big Short wrote about the transition,

The first time Trump paid attention to any of this was when he read about it in the newspaper. The story revealed that Trump’s very own transition team had raised several million dollars to pay the staff. The moment he saw it, Trump called Steve Bannon, the chief executive of his campaign, from his office on the 26th floor of Trump Tower, and told him to come immediately to his residence, many floors above. Bannon stepped off the elevator to find Christie seated on a sofa, being hollered at. Trump was apoplectic, yelling: You’re stealing my money! You’re stealing my fucking money! What the fuck is this?

Seeing Bannon, Trump turned on him and screamed: Why are you letting him steal my fucking money? Bannon and Christie together set out to explain to Trump federal law. Months before the election, the law said, the nominees of the two major parties were expected to prepare to take control of the government. The government supplied them with office space in downtown DC, along with computers and rubbish bins and so on, but the campaigns paid their people. To which Trump replied: Fuck the law. I don’t give a fuck about the law. I want my fucking money. Bannon and Christie tried to explain that Trump couldn’t have both his money and a transition.

Shut it down, said Trump. Shut down the transition.
