Last month, FTX filed for bankruptcy in the US, leaving many users unable to withdraw their funds.It is unclear how much people who have funds in the exchange will get back at the end of bankruptcy proceedings - though many experts have warned it may be a small fraction of what they deposited.Besides accusing Mr Bankman-Fried of defrauding lenders, investors and customers, Mr Williams alleged he had used "tens of millions" in ill-gotten gains for illegal campaign contributions to Democrats and Republicans alike."All this dirty money was used in service of Bankman-Fried's desire to buy bipartisan influence and impact the direction of public policy in Washington," Mr Williams said.Mr Bankman-Fried also denied allegations he must have been aware that FTX's affiliated trading company, Alameda Research, was using FTX customer funds."
