Since Sam Bankman-Fried was convicted of fraud last year, he has hired a new lawyer known for courtroom showmanship. A group of sympathetic law professors has pushed for a reappraisal of his actions. And his parents have turned for help to former employees of FTX, the collapsed cryptocurrency exchange he founded. From a federal detention center in Brooklyn, Mr. Bankman-Fried, 31, has continued to fight his case behind the scenes, as he argues for a lenient sentence and prepares to appeal his conviction. Since last year’s trial, Mr. Bankman-Fried has hired Marc Mukasey, who once represented former President Donald J. Trump, to oversee his sentencing, as well as a separate lawyer at the law firm Shapiro Arato Bach to handle the appeal.
