Studies have shown no connection between COVID-19 vaccination during pregnancy and increased risk of miscarriage. Despite this, Republican Sens. Rand Paul and Ron Johnson resurrected a long-debunked claim of an astronomical rate of miscarriage after vaccination while also accusing Dr. Anthony Fauci of deceiving the public about the safety of the shots during pregnancy.
During the signing of an executive order on vaccines, President Donald Trump and Health and Human Services Secretary Robert F. Kennedy Jr. made a deluge of false and misleading claims about the U.S. childhood vaccine schedule.
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.
President Donald Trump has blamed improper forest management for Canadian wildfires whose smoke drifted into the Midwestern and Northeastern U.S. earlier this month.

Health and Human Services Secretary Robert F. Kennedy Jr. has baselessly tied alleged declines in sperm counts among teenagers to a “fertility crisis” or an “explosion in infertility.”
President Donald Trump has repeatedly blamed vandals for damaging the new blue lining of the Lincoln Memorial Reflecting Pool, which is now peeling, as well as for algae in the water.

President Donald Trump has touted more than $500 billion in prescription drug savings over 10 years from his policies. But the savings are largely aspirational, and not based on the more limited actions the administration has taken so far.
In a May 16 Truth Social post, President Donald Trump cited updated climate change scenarios to misleadingly claim that experts had “admitted” prior climate change projections “were WRONG! WRONG! WRONG!” The regularly scheduled revision reflects in part the progress the world has made on moving away from fossil fuels.
The Food and Drug Administration in recent months has approved a small number of drugs quite quickly under a new expedited review program. But Health and Human Services Secretary Robert F. Kennedy Jr. has overstated the impact of the program by making misleading comparisons to the pace of drug approvals in the past.
In the midst of a court battle over whether to continue to allow access by mail to the medication abortion pill mifepristone, Republican lawmakers have claimed that 10% or more of women who take the drug have serious side effects. A 2025 report from an anti-abortion group that put forward the figure has been criticized by reproductive health researchers for methodological issues and a lack of transparency about its data source.
