Congressional Democrats are calling on the largest U.S. banks to disclose information about how they plan to handle the risks posed by fast-changing AI capabilities.
Rep. Maxine Waters of California, the top Democrat on the House Financial Services Committee, requested details from bank CEOs about how they plan to guard against the potential cyber threats that Mythos, an artificial intelligence model from Anthropic, and other sophisticated models could bring.
"I am deeply concerned that the Committee has not been briefed by your banks on how you are confronting the heightened risks of cybersecurity vulnerabilities identified by Mythos," Waters wrote in a letter on Monday to the CEOs of Goldman Sachs, Morgan Stanley, JPMorgan Chase, Bank of America, Wells Fargo, and Citigroup.
Waters requested information by July 3 about their efforts -- including what kinds of AI frameworks the firms are developing on their own, and whether they may now require enhanced security measures.
The congresswoman's request followed letters this month from Sen. Elizabeth Warren of Massachusetts to Sen. Tim Scott (R., S.C.) and Treasury Secretary Scott Bessent about how regulators and lawmakers were handling of cybersecurity threats posed by AI.
Warren, the top Democrat on the Senate Banking, Housing, and Urban Affairs Committee, criticized the Trump administration's increasingly hands-off approach to bank supervision -- which banks have lobbied for in recent years -- at a time when AI models are growing more powerful.
"It is deeply troubling that Treasury's Wall Street deregulation agenda is leaving the financial system increasingly vulnerable to AI-enabled cyber threats, as the bank examiner workforce has been slashed and supervisory authorities used to police unsafe cyber practices are being curtailed," Warren wrote in a letter to Bessent.
On Tuesday, Anthropic released a "Mythos-class" model it says is safe for general use. It also released a separate capability called Claude Mythos 5 that it will initially deploy through a partnership called Project Glasswing, a group that includes blue-chip companies such as JPMorgan, Apple, and Microsoft.
Spokespeople for Wells Fargo, JPMorgan, and Citi declined to comment. The Treasury Department, Goldman Sachs, Morgan Stanley, and Bank of America didn't respond to requests for comment.
