An appeals court reduced Trump’s bond by more than 60% after his attorneys claimed it was a “practical impossibility” to pay the full amount. Their failure to disclose a proposal from a billionaire financier may have violated ethics rules.

In an interview with ProPublica, billionaire California financier Don Hankey said he reached out to Trump’s camp several days before the bond was lowered, expressing willingness to offer the full amount and to use real estate as collateral.

“I saw that they were rejected by everyone and I said, ‘Gee, that doesn’t seem like a difficult bond to post,’” Hankey said.

However, legal experts told Business Insider, that if his lawyers knew about the offer and failed to notify the court, they may have violated ethics rules.
