A crypto industry advocacy group is pushing the Office of the Comptroller of the Currency (OCC) to defend recent national bank charter approvals for cryptocurrency firms after U.S. Sen. Elizabeth Warren criticized the process as potentially unlawful. Multiple outlets report that The Digital Chamber has rejected Warren’s assertions that companies such as Coinbase and Ripple received approvals through improper actions or in violation of banking laws. The group is asking the OCC to stand by its decisions regarding the applications and to respond to the senator’s claims.

The reporting centers on Warren’s allegation that the Comptroller may have violated U.S. banking regulations when approving trust or related charters for crypto businesses. In response, The Digital Chamber frames the OCC actions as legitimate and challenges the characterization that the regulator acted outside the law.

While the sources describe the dispute, they focus primarily on the advocacy group’s response and the senator’s criticism rather than providing new legal findings or rulings. The issue is presented as an ongoing policy and regulatory controversy involving congressional scrutiny and the OCC’s authority to approve financial charters for crypto firms.
