Health and environmental organizations filed a lawsuit against the Environmental Protection Agency (EPA) and its administrator, Lee Zeldin, in response to the recent rescission of the "endangerment finding" from 2009. This historic scientific finding established that greenhouse gases pose a danger to public health and has been the legal basis for all U.S. climate policies under the Clean Air Act for the last 15+ years. While the Trump administration claims that the endangerment finding "strangled" the economy and car industry through overregulation, the plaintiffs, which include the American Lung Association and the Sierra Club, claim that the rescission is scientifically unjustified and violates the law by voiding essential emissions controls for cars and power plants. This rescission has been described as the biggest rollback of federal power over climate change in U.S. history.
