A law firm representing anti–wind energy groups is demanding that Brown University researchers retract findings linking those groups to the fossil fuel industry, The New York Times reported Monday. 

The move comes weeks after Brown reached an agreement with the Trump administration. The government restored $510 million in frozen federal research grants after the university agreed to certain demands, including adopting the Trump administration’s definitions of male and female and turning over admissions data. 

The Trump administration has halted or canceled thousands of other research grants across the country, including many focused on climate change.

Marzulla Law LLC characterized the research published by Brown’s Climate and Development Lab as “false and injurious” in an Aug. 11 letter to Brown’s general counsel. It threatened to file complaints with Brown’s public and private funders, including the Energy Department, the National Science Foundation and the Mellon Foundation. 

A university spokesperson did not comment specifically on the law firm’s demands but told the Times that it’s committed to maintaining academic freedom. 

Brown researchers who authored a case study about Marzulla Law have written that the firm has “a history of advancing anti-environmental lawsuits and significant ties with the fossil fuel industry.” Researchers have also published findings accusing one of the firm’s clients—the nonprofit Green Oceans, which is trying to shut down the construction of a nearly complete $4 billion wind farm off the coast of Rhode Island—of being part of “a fossil-fuel-funded disinformation network.”

On Friday, the Trump administration, which opposes the wind energy industry, halted the wind farm project without citing specific reasons.
