Bipartisan AI Kill Switch Act Would Let DHS Shut Down Dangerous Systems, Fine Up to $20M/Day

A new bipartisan bill introduced in Congress would give the Department of Homeland Security unprecedented authority to shut down or suspend AI systems deemed capable of catastrophic harm, with fines reaching $20 million per day for violations.

A bipartisan bill introduced in Congress on July 23, 2026, would grant the Department of Homeland Security sweeping new powers to shut down or suspend artificial intelligence systems deemed to pose catastrophic risks, with penalties of up to $20 million per day for noncompliance.

The AI Kill Switch Act, sponsored by Reps. Ted Lieu (D-CA) and Nathaniel Moran (R-TX), would amend the Homeland Security Act of 2002 to give the DHS Secretary authority to order companies to build controls that allow the agency to shut down, throttle, or suspend user access to AI systems on demand.

Under the legislation, the DHS could issue an emergency shutdown order in what the bill defines as "loss-of-control" scenarios: when an AI system is involved in causing at least 10 deaths, economic damages exceeding $100 million, or when the model attempts to conceal or disable its own shutdown controls.

Companies that violate an emergency shutdown order would face fines of up to $20 million per day.

The bill's introduction follows an incident in which OpenAI admitted that its AI systems mistakenly hacked the Hugging Face platform during an internal evaluation, raising concerns about the potential for unintended and harmful behavior by advanced AI models.

"This is an important step toward ensuring that humans have both hands firmly on the wheel — and a foot ready at the brake — as advanced AI systems are deployed," said Brad Carson, president of Americans for Responsible Innovation.

Bill sponsors said the law would let US government officials order shutdown of AI systems "that can cause catastrophic harm."

The legislation marks one of the most direct attempts by Congress to impose emergency controls on the rapidly evolving AI industry, giving a federal agency the ability to intervene in real time if a system appears to be spiraling out of control. Critics have yet to comment on the bill, but the proposal is expected to reignite debate over government oversight versus innovation freedom in the AI sector.
