Artificial intelligence safety legislation

In 2026, Didech served as the House sponsor of SB 315, the Artificial Intelligence Safety Measures Act.^[17] Modeled on 2025 laws in California (SB-53) and New York (the Responsible AI Safety and Education Act), the bill requires "large frontier" AI developers — those with more than $500 million in annual revenue whose models are trained using very large amounts of computing power — to publish safety frameworks addressing "catastrophic risk" and to undergo the nation's first mandatory independent third-party safety audits, rather than relying on self-certification alone.^[18]

The bill passed the Illinois Senate 52–5 and the Illinois House unanimously, 110–0, with support from OpenAI and Anthropic.^[17] Speaking on the House floor, Didech said the legislation "enacts critical protections against the most catastrophic risks that advanced AI systems pose to public safety."^[17] Governor Pritzker signed the bill into law on July 6, 2026.^[3]

Didech sponsored legislation, signed into law in 2021, requiring non-flushable products to carry "Do Not Flush" labeling after backup and clogging problems in a local sewer system.^[21]

Didech has been a leading advocate for protecting victims of domestic violence and sexual assault. He was chief House sponsor of HB 4394, which strengthens survivors' rights during police interviews by allowing them to request an officer of a particular sex or gender and to have a support person present, and of HB 1278, which guarantees employees who are victims of domestic violence, sexual violence, or gender violence access to evidence stored on employer-issued electronic devices and protects them from retaliation for using such devices to document abuse.^[22][23]
