Sen. Warren requests financial disclosures from Trump’s crypto czar

Massachusetts Senator Elizabeth Warren, ranking member of the Senate Banking Committee, is asking for White House AI and Crypto Czar David Sacks to back up his claims that he no longer holds any digital assets.

In a March 6 letter to Sacks, Sen. Warren suggested US President Donald Trump and “other private individuals” would directly benefit from the executive branch’s digital asset policies. She expressed concerns about Sacks’ potential conflicts of interest, requesting he make any financial disclosures with the Office of Government Ethics public and provide information about his purported status as a “special government employee.”

Sen. Warren cited Sacks’ involvement with the administration since Trump announced his appointment as a crypto czar in December 2024. The US president signed an executive order in January to form a working group exploring digital asset regulation — chaired by Sacks — including a US crypto stockpile. 

Trump said at the executive order signing that Sacks was going to “make a lot of money,” suggesting that he would personally benefit from government policies he was overseeing. On March 2, the US president announced he had directed the working group to include XRP (XRP), Solana (SOL) and Cardano (ADA) in the crypto reserve, in addition to Bitcoin (BTC) and Ether (ETH), which Sacks held but claimed to have sold before Jan. 20.
