There’s also the question of who has actually been paying for the lawyers. I don’t think Trump is paying them out of his own pocket.
I’m pretty sure it has been his campaign committee, at least as of the last report I am aware of from 11/23. It had paid Jones Day a little over $10 million at that point, although I think much of that was from before the election. More often than not, Trump’s campaign committee was the plaintiff rather than Trump himself, such as in the Pennsylvania federal case.
He reportedly raised over $200 million after the election, but reportedly most of that went to his PAC. Certainly not much of that went to litigation.
