US Senator Ruben Gallego criticised a Republican counterproposal to the CLARITY Act, calling it "not a serious effort."
The comments came as lawmakers continued negotiations over legislation for the cryptocurrency industry.
Gallego said both parties should work towards legislation that can gain broad support in Congress.
The debate focuses on how cryptocurrencies should be regulated and which agencies should oversee the industry.
The CLARITY Act aims to establish clearer rules for digital assets in the United States.
Lawmakers have continued negotiations as the crypto industry pushes for greater regulatory certainty.
