So, let's unpack this a little bit.
1. An ACLU executive meets with a billionaire ELON MUSK, who happens to be one of ACLU's top donors, per his own claim. Elon tells him his girlfriend might've sent them a check (wink, wink).

2. The executive receives an ANONYMOUS check from a foundation financed by MUSK.
3. He writes to the girlfriend: "I'm guessing YOU want me to apply that amount to the overall pledge" It's your money, right? RIGHT?

4. Girlfriend: of course it was from me. Ignore than it wasn't send from my account, it's still my money. Elon's fund and my pocket are basically the same, you know?

And this, dear children, is why we need to look very closely at ACLU's accounting books. Because that guy just admitted he was going "code things into right databases" based on an email claim, not the checks he received.
