Senate Minority Leader Chuck Schumer sent a letter to DHS Secretary Markwayne Mullin Thursday pressing the department to coordinate AI cybersecurity defenses with state, local, tribal, and territorial governments — before, as he put it, "there are any major disruptions to hospitals or energy grids — or worse." The letter follows Anthropic's limited release of Mythos, a model capable of identifying decades-old security vulnerabilities that the company declined to release publicly.
Schumer's sharpest punch: CISA still has no Senate-confirmed director under the second Trump administration. He also flagged DHS's decision to suspend funding for the Multi-State Information Sharing and Analysis Center — the primary cyber-sharing resource for sub-federal governments — mid-transition to an unspecified new model.
The play here is straightforward. Schumer gets credit for ringing the alarm while the administration owns every day the CISA director's chair stays empty. A hospital ransomware event lands differently when the paper trail shows Democrats asked and Republicans shrugged.
