NASSAU, Bahamas/NEW YORK (Reuters) -U.S. prosecutors on Tuesday accused Sam Bankman-Fried, the founder and former CEO of crypto currency exchange FTX, of fraud and violating campaign finance laws by misappropriating his customers' funds, saying the investigation is ongoing and "moving very quickly." U.S. Attorney Damian Williams in New York said Bankman-Fried made illegal campaign contributions to Democrats and Republicans with "stolen customer money," saying it was part of one of the "biggest financial frauds in American history." "While this is our first public announcement, it will not be our last," he said, adding Bankman-Fried "made tens of millions of dollars in campaign contributions."
