FTX said in a court filing in Wilmington, Delaware, late on Wednesday that the DOJ's proposed review would only add cost and delay to its bankruptcy case.
As part of its own investigation, FTX asked U.S. Bankruptcy Judge John Dorsey, who is overseeing its Chapter 11 proceedings, to help it secure documents from Bankman-Fried, members of his family and other insiders with information about FTX transactions that used "misappropriated and stolen" funds.
FTX is also seeking information about political donations by Mind the Gap, a political action committee founded by Barbara Fried, and Guarding Against Pandemics, an advocacy organization founded by Sam Bankman-Fried and his brother, Gabriel Bankman-Fried.
The U.S. Department of Justice's bankruptcy watchdog has called for an independent investigation into its collapse, a request that received backing from a bipartisan group of U.S. senators.
Sam Bankman-Fried, who has been accused of stealing billions of dollars from FTX customers to pay debts incurred by his crypto-focused hedge fund, has pleaded not guilty to fraud charges.
