Missouri Senate debates AI guardrails, adopts amendments and lays bill over

The Missouri Senate debated a broad package of artificial intelligence rules and protections and adopted several amendments before the sponsor laid the bill over on the informal calendar.

The senator from the eleventh, sponsor of the senate committee substitute for SB 1012, told colleagues the measure is intended to put "guardrails on artificial intelligence" while allowing the technology to be used as a tool. The sponsor said the bill requires human oversight, mandates consumer notice when people interact with AI, adopts liability rules that assign responsibility to people rather than machines, and uses the federal definition of AI (referenced in the bill as a US Code citation) to set state standards. "We need to put some, at least, initial guardrails around artificial intelligence," the senator from the eleventh said.

Lawmakers adopted four floor amendments by voice vote. Senate amendment 1, offered by the senator from Lawrence, replaces a severability clause and provides that, "to the extent that this section is inconsistent with any provision of federal law, the relevant provision of Federal law shall prevail." The senator from Lawrence described the amendment as an attempt to give federal law deference in cases of conflict.

Senate amendment 2, offered by the senator from Stone and described in debate as the "Guard Act," directs age-verification requirements, bans AI companion products marketed to minors, mandates periodic disclosure that a product or service is nonhuman, and creates criminal penalties aimed at companies that knowingly or recklessly provide companion chatbots that solicit explicit conduct from minors or encourage self-harm. In floor exchanges, senators asked whether classroom uses or benign educational tools would be affected; the sponsor said the amendment is not intended to prohibit instructor-led uses of AI in education and emphasized the goal of protecting children from harmful "companion" chatbots.

Senate amendment 3 adds language preventing professional licensing boards (including the board of registration for the healing arts, the Missouri Dental Board, the board of nursing and the board of pharmacy) from using rulemaking to permit AI to dispense medications or to replace licensed professionals in those functions. Supporters said the amendment is a guardrail that preserves human accountability in medical and pharmaceutical decision-making.

Senate amendment 4, offered by the senator from the fifteenth, would prohibit confidentiality clauses in settlements arising from complex emerging-technology disputes so that systemic harms are not shielded from public view; the senator from the eleventh said he strongly supported the transparency measure.

Debate extended when several senators raised concerns about a presidential executive order they said could create pressure on states by identifying certain state AI laws as onerous and, potentially, making states ineligible for some federal broadband deployment funds. The sponsor of SB 1012 argued an executive order has no force of law and reiterated that state legislators were elected to protect citizens' rights; other senators warned that aggressive state rules could jeopardize federal funding for rural broadband deployments. A point of order was raised and later withdrawn.

After the amendments were adopted and additional debate, the sponsor asked to lay the bill over on the informal calendar; the motion was agreed to and SB 1012 was placed on the informal calendar with no recorded roll-call tally (the transcript records voice votes). The bill therefore advanced in amendment form but will return for further action in committee or on the floor.

The floor debate included several specific claims and statistics cited by the sponsor, including job-displacement figures and news reports about AI-driven harms; those figures were presented by the sponsor as part of his rationale for state action.

Next steps: SB 1012 was laid over on the informal calendar; further committee consideration or a future floor action is expected before final passage or referral.
