Bankman-Fried has retained Cohen, of Cohen & Gresser, Bankman-Fried's spokesperson Mark Botnick said in an emailed statement.
In recent weeks, U.S. authorities have sought information from investors and potential investors in FTX, according to two sources with knowledge of the requests.
Federal prosecutors in New York are asking for details on any communications such firms have had with the crypto firm and its executives, including Bankman-Fried, the sources said.
The Securities and Exchange Commission has been asking for similar information from investors as well, one of the sources said.
"I didn't ever try to commit fraud," Bankman-Fried said, adding that he doesn't personally think he has any criminal liability.
