Former FTX CEO Sam Bankman-Fried will no longer be represented by his legal counsel at Paul, Weiss, Rifkind, Wharton & Garrison, a white-shoe law firm, less than a week after retaining the firm to represent him.

Semafor reported on Thursday that Bankman-Fried will now be represented by David Mills, a criminal law and white-collar crime professor at Stanford University’s law school – where Bankman-Fried’s father, Joseph Bankman, also teaches law. It was not clear whether Bankman-Fried had parted ways with Martin Flumenbaum, his attorney, or if the law firm had dropped him as a client.
