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. There’s no evidence for those claims, and the vaccine has been well-studied for several decades.

RFK Jr.’s Falsehood-Filled CNN Interview
In a contentious interview on CNN’s “State of the Union,” Health and Human Services Secretary Robert F. Kennedy Jr. made several false, misleading and baseless claims about the origins of Lyme disease and the respiratory syncytial virus, the COVID-19 pandemic, and what the science shows about autism, vaccination and acetaminophen use during pregnancy.
Paul Distorts Fauci’s Diary Entry About COVID-19 and Wet Market
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.
FactChecking Trump’s Election Security Speech
Democrats’ and Republicans’ Screwworm Blame Spin
Politicians of both political parties have blamed either the Trump or the Biden administration for the arrival of the New World screwworm, a flesh-eating fly that affects the cattle industry, in the U.S. after decades of eradication. But experts say the reasons are different or more complicated than either side is saying — and that it’s no one administration’s fault.
A Timeline of RFK Jr.’s Mixed Messaging on the Measles Vaccine
In defending his record on measles, Health and Human Services Secretary Robert F. Kennedy Jr. twice said during a recent Senate hearing, “We promote” the measles vaccine. While it’s true that the Centers for Disease Control and Prevention continues to recommend the shot, Kennedy has rarely made an unequivocal endorsement of it, even as the nation has seen an alarming rise in measles cases.
The Persistent Misleading Claim That Vaccines Aren’t Properly Tested for Safety
It’s a common, misleading refrain in anti-vaccine circles: Childhood vaccines may be unsafe because few if any have been tested in placebo-controlled trials before being approved. But that claim misunderstands the vaccine safety testing process and takes advantage of a narrow definition of a placebo, scientists told us.
EPA’s Misleading Claim of $1.3 Trillion in Deregulatory ‘Savings’
Trump administration officials have claimed that they are saving Americans over $1.3 trillion by ending regulation of greenhouse gas emissions from cars and trucks. But the figure does not incorporate any benefits of the emissions standards. By one of the Environmental Protection Agency’s own calculations, getting rid of the standards could cost billions.

During her confirmation hearing to become surgeon general, Dr. Casey Means had various back-and-forths with senators, who pressed her on topics related to vaccines, her qualifications and disclosure of her conflicts of interest.
