A bipartisan duo unveiled a bill Tuesday to regulate artificial intelligence chatbots to protect children, as legislators continue to debate rules for the fast-moving technology.

The bill, authored by Sens. John Curtis (R-UT) and Adam Schiff (D-CA), would strengthen requirements for existing rules by creating a federal framework that requires AI systems to implement child-safety-by-design, establish parental controls, avoid child-targeted advertising, and prevent the sale or sharing of children’s personal information.
