U.S. Senator Elizabeth Warren has renewed her push for tighter oversight of the cryptocurrency sector, urging federal authorities to launch another national security investigation into decentralized finance, with a specific focus on PancakeSwap. In a letter sent Monday to Treasury Secretary Scott Bessent and Attorney General Pam Bondi, Warren raised concerns that the decentralized exchange may be amplifying digital tokens connected to World Liberty Financial Inc., a crypto company linked to President Donald Trump.
Warren argued that PancakeSwap, a major decentralized exchange operating across multiple blockchains and closely associated with Binance’s blockchain ecosystem, should be reviewed for potential links to improper political influence. She questioned whether enforcement decisions could be affected by the Trump administration’s ties to crypto-related business interests, echoing a similar request she supported last month that also centered on World Liberty Financial.
The Massachusetts senator emphasized that the inquiry is especially important as Congress debates crypto market structure legislation. Lawmakers are currently considering rules aimed at preventing terrorists, criminal organizations, and hostile states from exploiting decentralized finance platforms. Warren, the ranking Democrat on the Senate Banking Committee, said it is critical to understand whether regulators are fully investigating risks associated with DeFi platforms that process hundreds of millions of dollars in daily transactions without requiring user identification.
Despite her longstanding criticism of the crypto industry, Warren has largely been sidelined in ongoing negotiations, as several Democrats have chosen to work with Republicans on broader crypto regulation. Those talks failed to deliver legislation before the end of the year, and Senate Banking Committee Chairman Tim Scott has indicated the issue will return to the committee’s agenda in January.
The debate over decentralized finance remains one of the most contentious issues in the bill, with industry leaders calling DeFi provisions a red line that could determine their support. Another unresolved point is a Democratic proposal to restrict senior government officials from holding crypto business interests, a measure the White House has already opposed.
If negotiations extend too far into the new year, they could clash with looming budget deadlines, potentially delaying crypto legislation once again amid broader congressional disputes.
