I'm inclined to believe this, not, per se, because his current lawyers say so - Trump has been able to find lawyers willing to lie for him or willing/too stupid to be duped into his whatever he's claiming. Whereas numerous pundits have been skeptical that Trump could raise roughly 1/2 billion dollars to post bond.
It'll be interesting to see how Trump's appeal plays out. If Trump were a random complainant without history in the courts - I rather suspect that he'd get some relief with regard to the bond - if only because it's such a high dollar amount.
But given Trump's history with the NY courts, perhaps - and possibly even likely - Trump's appeal will fail.
Stay tuned - interesting developments await.
