Trump Misleads on Climate Change and Renewables at U.N.
In an hourlong address before the U.N. General Assembly on Sept. 23, President Donald Trump lashed out at those promoting “the green energy agenda.” Along the way, he made numerous false and misleading claims about renewable energy and climate change, many of which we’ve fact-checked before.

News reports have indicated Health and Human Services Secretary Robert F. Kennedy Jr. may point to Tylenol and folate deficiency in his promised announcement on the causes of autism.

Q&A on the Trump EPA’s Effort to Curtail Regulation of Greenhouse Gas Emissions
The Environmental Protection Agency is holding public hearings this week on its effort to undo the legal foundation for its regulation of greenhouse gases, the heat-trapping gases that cause climate change. In a major policy shift announced in late July, the Trump administration EPA said it would rescind the so-called “endangerment finding,” which allows the agency to regulate such emissions, arguing that legal and scientific developments justify a reconsideration.
RFK Jr.’s Vaccine Court Spin
Health and Human Services Secretary Robert F. Kennedy Jr. misrepresented the country’s compensation program for those who are harmed by vaccines, alleging that it’s biased and corrupt and falsely claiming that a person can’t sue a vaccine company “no matter how negligent they are.” He also incorrectly said there is “zero incentive” for vaccine companies to produce safe vaccines.
