Health and Human Services Secretary Robert F. Kennedy Jr. told the Make America Healthy Again Summit in Washington on Sept. 29 that artificial intelligence can give Americans a second opinion better informed than any doctor.

Kennedy also said OpenAI CEO Sam Altman had told him it would be "malpractice" to diagnose without consulting AI, Forbes reported. A day earlier, McKinsey & Co. estimated that AI could perform the work behind 16% to 22% of U.S. outpatient claims, from low-complexity office visits to imaging interpretation. Smart ring maker Oura postponed its IPO on the eve of trading, and Penn Medicine opened OpenEvidence to 10,000 clinicians.

In California, Gov. Gavin Newsom's deadline to act on four health-AI bills, including limits on AI marketed as therapy, falls today. A University of Florida study found that five AI evidence-search tools each missed large shares of the published evidence on a clinical question.
