Sens. Elizabeth Warren (D-MA), Roger Marshall (R-KS), and John Kennedy (R-LA) sent a letter on December 5 criticizing San Diego-based crypto bank Silvergate for its role in potentially transferring funds between FTX and his hedge fund, Alameda Research, as part of FTX’s alleged use of customer funds to plug holes in Alameda’s balance sheet during this year’s crypto market crash. The letter says, “Your bank’s involvement in the transfer of FTX customer funds to Alameda reveals what appears to be an egregious failure of your bank’s responsibility to monitor for and report suspicious financial activity carried out by its clients.”
