US Environmental Protection Agency

Eighteen American youth are demanding that a court immediately halt the Trump administration’s repeal of the scientific finding underpinning virtually all US climate regulations.

The plaintiffs sued the Trump administration in February days after officials revoked the 2009 endangerment finding, which found that greenhouse gas pollution threatens public health and welfare. Filed in the Washington DC circuit court of appeals Venner v EPA alleges that the move infringes upon rights guaranteed by the US constitution, including to religious freedom, life and liberty.

A coalition of 24 states, alongside a dozen cities and counties, has sued the Trump administration over its decision to revoke the bedrock scientific determination underpinning virtually all US climate regulations.

More than 160 environmental and public health organizations on Tuesday called for Lee Zeldin, the Environmental Protection Agency (EPA) administrator, to resign or be fired.

We’ve seen it happen in vivid, documented detail — and the story starts with Anthropic itself. Dario Amodei and several of his colleagues founded Anthropic in 2021 after leaving OpenAI over concerns about the company’s approach to safety and the pace of AI development. That departure wasn’t an anomaly. It was the first chapter of a pattern that has only accelerated since. When OpenAI’s direction drifted further from its founding safety principles, the departures didn’t trickle — they cascaded. Ilya Sutskever, OpenAI’s co-founder and chief scientist, left in May 2024. Jan Leike, who co-led the Superalignment team, followed days later, writing publicly that safety had “taken a backseat to shiny products.” By August 2024, Fortune reported that nearly half of OpenAI’s AGI safety researchers had quietly resigned. Researcher Daniel Kokotajlo walked away from $1.7 million in equity — the vast majority of his family’s net worth — because he’d lost confidence the company would behave responsibly. Most recently, just weeks ago, OpenAI researcher Zoë Hitzig quit in a New York Times op-ed over the company’s move toward advertising, warning that ChatGPT’s archive of intimate user conversations created manipulation risks that “we don’t have the tools to understand, let alone prevent.”
