Friedberg gave details about FTX in a Nov. 22 meeting with two dozen investigators, the person said.
"THROUGH THICK AND THIN"Prior to his work advising FTX, Friedberg advised a mix of banking, fintech, and online gaming companies.
At the time, the source said Friedberg advised Bankman-Fried on running Alameda, which he founded that year.
In 2020, when Bankman-Fried launched a separate exchange for U.S. customers called FTX.US, Friedberg moved in-house as FTX's chief regulatory officer.
In a now-deleted blog post published that year on FTX's website, Bankman-Fried wrote that Friedberg was FTX's legal advisor "from the very beginning," noting he had been "with us through thick and thin."
