Sen. Schiff introduces bill restricting Defense Department AI use

UPI reports Sen. Adam Schiff (D-Calif.) introduced the Human Authority in Lethal Operations Act, a bill aimed at limiting the Department of Defense's use of AI in lethal strikes. Per UPI and The Hill, the bill would set oversight for autonomous and semi-autonomous weapons and AI-enabled surveillance systems, establish a clear chain of command under which a designated commander has final say over force decisions involving such systems, and require personnel to maintain records of their decision-making, including how targets are selected, for after-the-fact review. The Hill reports it would also bar the military from using AI to monitor individuals engaged in constitutionally protected activities, keep human involvement in nuclear-weapons decisions, and restrict purchases of Americans' personal data from third parties in some cases. UPI quotes Schiff: "There are good reasons to use AI technology to advance our national security," adding, "we cannot depend on technology alone to guide us, particularly when the risks of harm can be fatal."

The reporting describes procedural and recordkeeping requirements rather than model-level controls or technical thresholds. Teams building defense-adjacent AI should expect emphasis on auditability, human-in-the-loop authorization, traceable decision logs, and constraints on surveillance and data-acquisition use cases rather than prescriptive model architectures.

Proposals constraining military automation sit at the intersection of accountability, audit trails, and civil liberties. Limits on AI-enabled surveillance and on buying Americans' personal data are directly relevant to practitioners working across defense tooling, data governance, and privacy compliance.

Watch the published bill text for definitions of "autonomous" and "semi-autonomous," the scope of required records, and enforcement mechanisms. The Hill reports other Senate Democrats are seeking to attach AI constraints to the National Defense Authorization Act, so track those parallel efforts and the Defense Department's response once formal text is available.
