US lawmakers are pushing legislation that would prevent AI companies from selling sensitive health and location data. The proposal reflects growing concern that data brokers and AI systems can combine personal information in ways users did not expect.

The bill targets a gap between privacy law and AI product development. Health-related signals can come from apps, searches, location trails and other sources that may sit outside traditional medical privacy rules.

For AI companies, the proposal is another sign that data access will face tighter scrutiny as consumer applications become more personalized.
