French President Emmanuel Macron, Madonna and Leonardo DiCaprio were among the celebrities who distributed on social media at least a dozen different photos of fires that purported to illustrate a crisis in the Amazon rain forest.
The problem is they weren't taken this year, and many might not even be of the rain forest, the Washington Times reported.
Fact-checkers included the far-left Mother Jones and Agence-France Presse, which found some of the photos came from blazes in California, India and other places.
