Media Bias Fact Check selects and publishes fact checks from around the world. We only utilize fact-checkers that are either a signatory of the International Fact-Checking Network (IFCN) or have been verified as credible by MBFC. Further, we review each fact check for accuracy before publishing. We fact-check the fact-checkers and let you know their bias. When appropriate, we explain the rating and/or offer our own rating if we disagree with the fact-checker. (D. Van Zandt)

| TRUE | Claim via Social Media: The White House posted map of the Strait of Hormuz saying it is a new U.S. territory.
Lead Stories rating: True (Trump posted it.) |
| BLATANT LIE |
Claim by Robert F. Kennedy Jr.: A “recent” study “just came out” that “very strongly supports” splitting the MMR vaccine into separate measles, mumps and rubella shots.
FactCheck.org rating: False (There is no credible new study supporting that claim, and vaccine experts said there is no evidence that separating the MMR vaccine would make it safer.) RFK Jr. Falsely Claims New Evidence Supports Splitting MMR Vaccine |
| MOSTLY FALSE |
Claim via Social Media: An audit found more than 228,000 invalid or suspicious votes tied to Zohran Mamdani’s 2025 New York City mayoral win.
Reuters rating: Mostly False (The figure came from extrapolating a small voter-registration sample using flawed assumptions and a commercial database; the audit did not identify 228,000 unique unqualified voters or tie suspicious votes specifically to Mamdani.) |
| BLATANT LIE |
Claim by Donald Trump (R): Rising autism rates are tied to today’s larger childhood vaccine schedule.
The Dispatch rating: False (Research has found no relationship between vaccination and autism, and experts largely attribute increased autism diagnoses to broader criteria, better screening and improved detection.) |
| FALSE | (International: United Kingdom): A video shows a migrant saying “I want my money and my free house and English woman, it’s my dream”.
Full Fact rating: False (This video has been altered. In the original clip the man is speaking Arabic and does not say this.) Video of migrant saying he wants money, free house and English woman has been edited – Full Fact |
