Senator Warner Warns CISA Staff Cut by One-Third and Budget Faces 700 Million Dollar Reduction

BLUFCISA's workforce and budget cuts will likely produce a net reduction exceeding $500 million by September 2027, degrading federal cyber defense capacity faster than hiring can restore it.

Sen. Mark Warner (D-VA), Vice Chairman of the Senate Select Committee on Intelligence, on June 16 wrote CISA Acting Director Nick Andersen documenting that the Trump administration has cut roughly one-third of the agency's workforce since January 2025, predominantly senior career officials, alongside a proposed FY2027 budget reduction exceeding $700 million 12. Five of the ten CISA regional directors are currently serving in an acting capacity, and state and local officials have reported to Warner's office reduced responsiveness and disrupted service delivery from the agency 12. Warner concurrently wrote to DHS Secretary Markwayne Mullin and all 50 governors and introduced legislation to restore MS-ISAC funding after former Secretary Noem terminated the program and barred states from using federal grants for membership 1. CISA Acting Director Andersen has announced more than 300 new hires are underway, a response Warner's letter characterized as insufficient given the scale of losses 2.

Analysis
Both sources trace to Warner's own communications, providing no corroboration from outside his office for CISA operational capacity claims. The administration's consistent alignment across budget, personnel, and program decisions supports a likely net FY2027 reduction of $500 million or more by September 30, 2027. Moderate confidence reflects that final appropriations remain contingent on congressional negotiations. Warner's June 16 letter moved the record from monitored staffing attrition to formally documented congressional findings covering both the proposed cut and MS-ISAC termination. Appropriators may negotiate the proposed reduction below the threshold that triggers structural incapacity, but senior career attrition is irreversible on any near-term timeline. State CISOs should not wait for final appropriations to assess alternative coordination arrangements.
