United States Senator Elizabeth Warren has urged federal authorities to clarify whether decentralised finance platforms are under investigation as crypto legislation stalls.
Warren sent a letter to Treasury Secretary Scott Bessent and Attorney General Pam Bondi seeking details on potential probes.
The Massachusetts senator cited decentralised exchanges including PancakeSwap and Uniswap in her inquiry.
She asked whether agencies were “investigating significant national security risks posed by decentralised cryptocurrency exchanges like PancakeSwap.”
Warren requested a formal response by January 12.
She raised concerns about alleged money laundering activity linked to North Korea and decentralised platforms.
Warren also warned about what she described as improper political influence over selective crypto enforcement.
“As Congress considers crypto market structure legislation, it is critical to understand whether you are seriously investigating these risks,” Elizabeth Warren said.
“The public deserves to know whether you are investigating the serious risks identified by national security experts and the crypto industry itself,” she said.
The letter was sent as the US Senate prepared to adjourn for the holiday recess.
Lawmakers had expected progress on the Responsible Financial Innovation Act before year end.
Senate Banking Committee chair Tim Scott confirmed the bill’s markup hearing was delayed until 2026.
Warren said the lack of clarity could allow criminals, terrorists and rogue states to exploit DeFi.
She also cited reports linking PancakeSwap activity to World Liberty Financial tokens.
Some Senate Democrats have raised concerns about conflicts of interest tied to the crypto industry.
