The New York Times is reporting that President Trump’s nominee to head the Interior Department killed a major study in late 2017 that found three widely used pesticides posed an existential risk to 1,200 endangered species. The Times reveals that David Bernhardt— a former oil industry lawyer who was then the deputy secretary of the interior—canceled publication of a years-long study into the pesticides’ dangers just before the results were set to be made public. Bernhardt’s move benefited major pesticide makers including FMC Corporation and Dow AgroSciences. Dow was a major donor to President Trump, giving $1 million to his inaugural committee. On Thursday, David Bernhardt will testify to the Senate Committee on Energy and Natural Resources at his confirmation hearings.
