A federal judge in Washington temporarily barred Environmental Protection Agency Administrator Lee Zeldin from terminating billions of dollars in grants to climate groups after he expressed concern that the financial funding was riddled with waste and corruption.

U.S. District Judge Tanya Chutkan ruled Tuesday that Zeldin had not provided sufficient evidence to back his claims that federal grants handed out to Climate United, Coalition for Green Capital, and Power Forward Communities were a “$20 billion ‘gold bar’ scheme” characterized by“self-dealing and wasteful spending,” as well as “incidents of misconduct, conflicts of interest, and potential fraud.” President Donald Trump’s EPA further failed to give the climate groups sufficient notice or opportunity to respond to claims of corruption, Chutkan wrote.
