A pair of attorneys defending FTX founder Sam Bankman-Fried against one of the biggest white-collar prosecutions in decades are veterans of high-profile cases, including ones involving drug lord "El Chapo" and disgraced socialite Ghislaine Maxwell. Mark Cohen and Christian Everdell, former federal prosecutors who are now partners in the New York-based boutique firm Cohen & Gresser ... are up against hard-charging Justice Department lawyers who moved quickly to indict Mr. Bankman-Fried after FTX's collapse and secured two of his former top lieutenants as cooperating witnesses. The Manhattan U.S. attorney's office this past month charged Mr. Bankman-Fried with stealing billions of dollars from FTX customers while misleading investors and lenders connected to his crypto-trading firm Alameda Research. He faces charges of fraud, conspiracy, money laundering and campaign-finance violations and pleaded not guilty last week. Messrs. Cohen, 59 years old, and Everdell, 48, have already navigated their client through a thorny extradition from the Bahamas, where Mr. Bankman-Fried had been jailed after the Justice Department requested that local police arrest him. The two lawyers worked with local counsel to secure his transfer to U.S. custody while negotiating with federal prosecutors his pretrial release under a $250 million bond. They are now tasked with combing through voluminous and technical discovery, including documents relating to FTX investors, debtors and political campaigns.
