The Senate effort to pass the Digital Asset Market Clarity Act is facing renewed friction as crypto industry leaders press lawmakers to preserve Section 604 protections for non-controlling and open-source software developers, while bipartisan talks have also reopened disputes over crypto ethics guardrails and their enforcement. A bipartisan meeting with White House crypto council executive director Patrick Witt ended without agreement, and senators remain divided over ethics provisions tied to Trump's crypto business interests, related enforcement mechanisms, and whether the bill sufficiently addresses law-enforcement concerns. Senators Warner and Cortez Masto said they will not support the bill unless those concerns are resolved, adding pressure to legislation already facing a narrow Senate calendar.
