Shortly after Bankman-Fried agreed to nominate Ray, he received a "potential funding offer for billions of dollars to help make customers whole," Bankman-Fried wrote. But by then he was told it was too late to rescind the move.

Bankman-Fried, who was arrested earlier on Monday in the Bahamas, could not be reached for comment. Sullivan and Cromwell, FTX and John Ray were not immediately available for comment.
