What We Know About Pennsylvania’s Two ‘Measles-Associated’ Deaths
After the Pennsylvania Department of Health announced two cases of measles-related deaths in one county, the local coroner appeared to contradict the account. And in an ongoing spat with Pennsylvania Gov. Josh Shapiro, Health and Human Services Secretary Robert F. Kennedy Jr. has alleged that a Shapiro staffer may have even “fabricated” the deaths. We’ll lay out what we know.
RFK Jr. Falsely Claims New Evidence Supports Splitting MMR Vaccine
Following an executive order that called for breaking up the combination measles, mumps and rubella, or MMR, vaccine, Health and Human Services Secretary Robert F. Kennedy Jr. said that a “recent” study “just came out” that “very strongly supports” the idea. But there’s no evidence of any such credible study, past or present.
Wright’s Hairsplitting Statements About Canceled Energy Grants in Blue States
Energy Secretary Chris Wright has repeatedly denied that politics were involved in the termination of more than 280 grants last October. A court filing made public in July, however, shows that Energy Department lawyers admitted that the only reason why those awards and not others were canceled is that the grant recipients were in states that vote for Democrats.
Trump’s False MMR Vaccine Claims
In signing an executive order about childhood vaccines, President Donald Trump falsely suggested that the measles, mumps and rubella, or MMR, vaccine was unsafe and that splitting up the combination shot would reduce the number of children with autism.

Sen. Rand Paul has pointed to a line in Dr. Anthony Fauci’s diary to claim that the former director of the National Institute of Allergy and Infectious Diseases privately “knew” in January 2020 that the coronavirus did not come from a wet market, saying this contradicted Fauci’s public statements regarding a natural origin of the virus. That misconstrues Fauci’s original statement.
Democrats Overstate Role of Monitoring Program Change in Parasitic Outbreak
As a large outbreak of cyclospora has ravaged the Midwest, Democrats have frequently pinned blame on the Trump administration for terminating a monitoring program for the parasite. But the change to the program, called FoodNet, is unlikely to have played much of a direct role in the current outbreak, several food safety experts told us.
