On Tuesday, August 26, 2026, Pennsylvania confirmed two deaths due to measles in unvaccinated individuals. Following this announcement, Pennsylvania Governor Josh Shapiro (D) took to social media to blame Health and Human Services Secretary Robert F. Kennedy Jr. and the Trump administration for contributing to the measles outbreaks that led to these fatalities.
